JAVA 编写两个类定义的组成

JAVA 编写两个类定义的组成

使返回结果为另一个A类的对象（即不破坏实在参数的值) 当你把入参A对象的值修改了以后A就被修改了 不可能不破坏参数值

public class A {
private short i;
private char ch;
public A(short i, char ch) {
super();
this.i = i;
this.ch = ch;
}
public short getI() {
return i;
}
public void setI(short i) {
this.i = i;
}
public char getCh() {
return ch;
}
public void setCh(char ch) {
this.ch = ch;
}
@Override
public String toString() {
return "A [i=" + i + ", ch=" + ch + "]";
}

}
//测试类
public class TestObject {

public static void main(String[] args) {
// TODO Auto-generated method stub
A x1 = new A((short)12,'6');
A x2 = new A((short)62,(char)65);
System.out.println(x1.toString());
System.out.println(x2.toString());
System.out.println(b(x1).toString());
System.out.println(b(x2).toString());
}
public static A b(A a){
a.setI((short)(a.getI()+3));
a.setCh((char)(a.getCh()+3));
A x3 = new A(a.getI(),a.getCh());
return x3;
}
}
