Question

我在JAVA中有两个用于函数重载的类，即ABC和XYZ。 XYZ类具有函数重载方法，而ABC类具有主要方法。我已将文件保存为ABC.java。程序确实编译但在运行时显示“无法找到或加载主类ABC”的错误。我还附上了我的具体代码。

class XYZ
{
   void pqr(int a, int b)
   {
      int res = a*b;
      System.out.println("The result is "+res);
   }
   void pqr(String a, String b)
   {
     System.out.println("The concatenated string is "+a+b);
   }
   void pqr(int a, int b, int c)
{ 
int res = a+b+c;
    System.out.println("The final result is "+res);
}
}

class ABC

{
 public static void main(String[] args)
{
    XYZ a = new XYZ();
    a.pqr(10,20);
    a.pqr("Pratik","Paul");
    a.pqr(20, 40, 60);
 }

}

Answer 1

按照以下步骤

步骤1：

go the bin folder of Java from command prompt(I assume you are trying to run the program from command prompt).

ex: C:\Program Files\Java\jdk1.8.0_05\bin

步骤2：

javac <your ABC.java file with full path>

ex: javac C:\Test\ABC.java

similary do for XYZ.java

步骤3：

Go to C:\Test\ from command prompt and run,
java ABC

找不到或加载主class.java
