myclass.java

安装J2SDK,并练习设置path和classpath环境变量；编写一个打印出”HelloWorld”的Java Application程序

public class MyClass
{   private int val1,val2;
    public void myFun(int x,int y)
    {
       val1=x;
       val2=y;
       System.out.println("The sum is:"+(val1+val2));
    }
    public static void main(String[] args)
    {
      MyClass MyObj=new MyClass();
      MyObj.myFun(1,2);
    }
}
