[14]マイアプリ-3を作成
方法
方法は整理整頓の箱…!
public class AccountingMethodApp {
public static void main(String[] args) {
double valueOfSupply = Double.parseDouble(args[0]);
double expenseRate = 0.3;
double vatRate = 0.1;
double vat = getVAT(valueOfSupply, vatRate);
double total = valueOfSupply+vat;
double expense = valueOfSupply*expenseRate;
double income = valueOfSupply-expense;
double dividend1 = income*0.5;
double dividend2 = income*0.3;
double dividend3 = income*0.2;
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+vat);
System.out.println("Total : "+total);
System.out.println("Expense : "+expense);
System.out.println("Income : "+income);
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
private static double getVAT(double valueOfSupply, double vatRate) {
return valueOfSupply*vatRate;
}
}
これで、クラスに方法があります.
public class AccountingMethodApp {
public static double valueOfSupply = 10000.0;
public static double vatRate = 0.1;
public static void main(String[] args) {
double expenseRate = 0.3;
double vat = getVAT();
double total = valueOfSupply+vat;
double expense = valueOfSupply*expenseRate;
double income = valueOfSupply-expense;
double dividend1 = income*0.5;
double dividend2 = income*0.3;
double dividend3 = income*0.2;
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+vat);
System.out.println("Total : "+total);
System.out.println("Expense : "+expense);
System.out.println("Income : "+income);
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
private static double getVAT() {
return valueOfSupply*vatRate;
}
}
このようにしてグローバル変数を与えることができます.
public class AccountingMethodApp {
public static double valueOfSupply;
public static double vatRate;
public static double expenseRate;
public static double expense;
public static void main(String[] args) {
valueOfSupply = 10000.0;
vatRate = 0.1;
expenseRate = 0.3;
expense = getExpense();
double vat = getVAT();
double total = getTotal();
double income = getIncome();
double dividend1 = income*0.5;
double dividend2 = income*0.3;
double dividend3 = income*0.2;
print( dividend1, dividend2, dividend3);
}
private static void print(double dividend1, double dividend2,
double dividend3) {
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+getVAT());
System.out.println("Total : "+getTotal());
System.out.println("Expense : "+getExpense());
System.out.println("Income : "+getIncome());
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
private static double getIncome() {
double income = valueOfSupply-expense;
return income;
}
private static double getExpense() {
double expense = valueOfSupply*expenseRate;
return expense;
}
private static double getTotal() {
return valueOfSupply + getVAT();
}
public static double getVAT() {
return valueOfSupply*vatRate;
}
}
この方法で作ることができます.カテゴリ
クラスが相互に関連付けられる変数をメソッドに関連付けます
method <- class
class Accounting{
public static double valueOfSupply;
public static double vatRate;
public static double expenseRate;
public static double expense;
public static void print(double dividend1, double dividend2,
double dividend3) {
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+getVAT());
System.out.println("Total : "+getTotal());
System.out.println("Expense : "+getExpense());
System.out.println("Income : "+getIncome());
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
public static double getIncome() {
double income = valueOfSupply-expense;
return income;
}
public static double getExpense() {
double expense = valueOfSupply*expenseRate;
return expense;
}
public static double getTotal() {
return valueOfSupply + getVAT();
}
public static double getVAT() {
return valueOfSupply*vatRate;
}
}
public class AccountingClassApp {
public static void main(String[] args) {
Accounting.valueOfSupply = 10000.0;
Accounting.vatRate = 0.1;
Accounting.expenseRate = 0.3;
Accounting.expense = Accounting.getExpense();
double vat = Accounting.getVAT();
double total = Accounting.getTotal();
double income = Accounting.getIncome();
double dividend1 = income*0.5;
double dividend2 = income*0.3;
double dividend3 = income*0.2;
// anotherVariable = .. ;
// anotherMethod = ... ;
Accounting.print(dividend1, dividend2, dividend3);
}
}
イルケイ...それを等級に縛ることができます!≪インスタンス|Instance|emdw≫
クラスをコピーすることで、異なるデータ値と異なるメソッド値を持つコピーを作成できます.
class Accounting1{
public static double valueOfSupply;
public static double vatRate;
public static double expenseRate;
public static double expense;
public static void print(double dividend1, double dividend2,
double dividend3) {
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+getVAT());
System.out.println("Total : "+getTotal());
System.out.println("Expense : "+getExpense());
System.out.println("Income : "+getIncome());
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
public static double getIncome() {
double income = valueOfSupply-expense;
return income;
}
public static double getExpense() {
double expense = valueOfSupply*expenseRate;
return expense;
}
public static double getTotal() {
return valueOfSupply + getVAT();
}
public static double getVAT() {
return valueOfSupply*vatRate;
}
}
class Accounting2{
public static double valueOfSupply;
public static double vatRate;
public static double expenseRate;
public static double expense;
public static void print(double dividend1, double dividend2,
double dividend3) {
System.out.println("Value of supply : "+valueOfSupply);
System.out.println("VAT : "+getVAT());
System.out.println("Total : "+getTotal());
System.out.println("Expense : "+getExpense());
System.out.println("Income : "+getIncome());
System.out.println("Dividend 1 : "+dividend1);
System.out.println("Dividend 2 : "+dividend2);
System.out.println("Dividend 3 : "+dividend3);
}
public static double getIncome() {
double income = valueOfSupply-expense;
return income;
}
public static double getExpense() {
double expense = valueOfSupply*expenseRate;
return expense;
}
public static double getTotal() {
return valueOfSupply + getVAT();
}
public static double getVAT() {
return valueOfSupply*vatRate;
}
}
public class AccountingClassApp {
public static void main(String[] args) {
Accounting1.valueOfSupply = 10000.0;
Accounting1.vatRate = 0.1;
Accounting1.expenseRate = 0.3;
Accounting1.expense = Accounting1.getExpense();
double vat = Accounting1.getVAT();
double total = Accounting1.getTotal();
double income = Accounting1.getIncome();
double dividend1 = income*0.5;
double dividend2 = income*0.3;
double dividend3 = income*0.2;
// anotherVariable = .. ;
// anotherMethod = ... ;
Accounting1.print(dividend1, dividend2, dividend3);
// ..
Accounting2.valueOfSupply = 20000.0;
Accounting2.vatRate = 0.1;
Accounting2.expenseRate = 0.3;
Accounting2.print(dividend1, dividend2, dividend3);
}
}
なんだ.仕事させろ!Accounting a1 = new Accounting();
a1.valueOfSupply = 10000.0;
a1.vatRate = 0.1;
このようにしてインスタンスを作成します.classのstaticはすべて出してから使用できます.
