Что тут делает метод format ?
return String.format("The user's name is %s, id = %d", name, id);
package com.javarush.task.task13.task1306;
/*
Баг в initializeIdAndName
*/
public class Solution {
public static void main(String[] args) throws Exception {
System.out.println(Matrix.NEO);
System.out.println(Matrix.TRINITY);
}
static class Matrix {
public static DBObject NEO = new User().initializeIdAndName(1, "Neo");
public static DBObject TRINITY = new User().initializeIdAndName(2, "Trinity");
}
interface DBObject {
DBObject initializeIdAndName(long id, String name);
}
static class User implements DBObject {
long id;
String name;
public DBObject initializeIdAndName(long id, String name) {
this.id = id;
this.name = name;
return this;
}
@Override
public String toString() {
return String.format("The user's name is %s, id = %d", name, id);
}
}
}
