Java 复制构造函数
java programming java8object oriented programming
Java 没有显式的复制构造函数，但我们可以模拟其行为。请参见以下示例 −
示例
public class Tester {
private String message;
public Tester(String message){
this.message = message;
}
public Tester(Tester tester){
this.message = tester.message;
}
public String getMessage(){
return message ;
}
public void setMessage(String message){
this.message = message;
}
public static void main(String[] args) {
Tester tester = new Tester("Welcome");
System.out.println(tester.getMessage());
Tester tester1 = new Tester(tester);
System.out.println(tester1.getMessage());
}
}
