studequ.java

用java编写的一些初级代码

public class StudEqu 
{
    int age;
    String name;
    public boolean equals(Object obj)
    {
	StudEqu st=null;
	if (obj instanceof StudEqu)
	    st=(StudEqu) obj;
	else
	    return false;
	return (st.age==this.age && st.name==this.name);
    }
    public static void main (String[] args)
    {
	StudEqu b=new StudEqu();
	b.name="cat";
	b.age=2;
	StudEqu a=new StudEqu();
	a.name="cat";
	a.age=2;
	System.out.println(b.equals(a));
    }
}
