getMethod()とinvoke()メソッドの適用

簡単なニーズの実装:プログラムでクラスのメソッドを呼び出し、結果println()を返します.実装方法:
MethodTest.java

import java.util.ArrayList;
import java.util.List;
import java.lang.reflect.Method;
import java.lang.reflect.InvocationTargetException;

        //            （）
        String methodName = "getInvoiceSortCode";
