java关键字 this 用法

Learn Java Tutorial 1.28 - Using "this" in Java

local variables和instance variables重名

public class Travis {
  int age;
  public Travis (int age) {
    this.age = age;
  }
  public static void main(String[] args) {
    Travis t = new Travis(24);
  }

调用类中其他的构造方法

public class Travis {
  int age;
  public Travis (int age) {
    this(age, "Travis");
  }
  public Travis(int age, String name) {
    this.age = age;
    System.out.print ( name + "" + age);
  }
  public static void main(String[] args) {
    Travis t = new Travis(24);
  }
