命令行无法打印某些打印语句

Question

所以我有一个程序，它在一行中打印出一个存储在对象中的变量。它在我尝试过的任何IDE（blue-J和Eclipse）中运行得非常好，但是当我在cmd中运行它时它只是空白，任何想法出了什么问题？

Answer 1

ohh i think command line has small limits on words to display the and i think the first print was covered by the second print you should use println or do something like this :

System.out.println(ans + " with score " + smallestAccept[i].getScore());

Answer 2

试试这个：

System.out.println(ans);
System.out.print(" with score: " + smallestAccept[i].getScore() + "\n");

或者这个：

@JsonIdentityInfo(generator=ObjectIdGenerators.PropertyGenerator.class, 
        property="name", scope=Player.class)
public class Player
{
    public String name;

    public Player() {}
    public Player(String name) { this.name = name; }

    public String toString() {
        // prints name and java object id 
        return name + "-" + super.toString();
    }
}
