class A
{
public int i;
public A(int i)
{
this.i = i;
}
public boolean equals(Object obj)
{
A aa = (A)obj;
if(this.i == aa.i)
return true;
else
return false;
}
}
public class TestStringEquals
{
public static void main(String[] args)
{
A aa1 = new A(2);
A aa2 = new A(2);
System.out.println(aa1);
System.out.println(aa2);
System.out.println( aa1.equals.(aa2) );
if(aa1 == aa2)
System.out.printf("aa1和aa2ppp\n");
else
System.out.printf("aa1和aa2xxx\n");
}
}
下面是出错信息:
D:\java1>javac TestStringEquals.java
TestStringEquals.java:30: : Ҫ<ʶ>
System.out.println( aa1.equals.(aa2) );
