来源：百度文库 编辑：神马品牌网 时间：2024/04/29 08:21:25
public class Alone5_6{
int a;
double b;
String c;
public Alone5_6(){ //调用x1行的构造函数
}
public Alone5_6(int a){ //调用x1行的构造函数
}
public Alone5_6(int a,double b){ //调用x1行的构造函数
}
public Alone5_6(int a,double b,String c){ //x1
}
int getA(){
}
double getB(){
}
String getC(){
}
}
随便谢谢，LZ看着办。
public class Alone5_6{
int a;
double b;
String c;
public Alone5_6(){ //调用x1行的构造函数
a = 0;
b = 0.0;
c = "";
}
public Alone5_6(int a){ //调用x1行的构造函数
this.a = a;
b = 0.0;
c = "";
}
public Alone5_6(int a,double b){ //调用x1行的构造函数
this.a = a;
this.b = b;
c = "";
}
public Alone5_6(int a,double b,String c){ //x1
this.a = a;
this.b = b;
this.c = new String(c);//此处视情况，如果需要使成员变量与参数指向同一内存地址，那么改为 this.c = c;
}
int getA(){
return a;
}
double getB(){
return b;
}
String getC(){
return c;
}
}
这不就是个javabean吗?
public class Alone5_6{
int a;
double b;
String c;
public int getA(){
return a;
}
public void setA(int a){
this.a = a;
}
public double getB(){
return b;
}
public void setB(double b){
this.b = b;
}
public String getC(){
return c;
}
public void setC(String c){
this.c = c;
}
上楼的回答就可以了。还等什么？
