Question

我正在尝试使用Jansi Java库在CMD / Console中使用颜色，我遇到了一个小问题。当我使用Jansi Library并尝试使用print f语句

时

System.out.printf("Hello young lad! What is thy " + RED + "name " + WHITE + "you were given at birth?\n>> ");

“＆gt;＆gt;”最后不打印。而是调用扫描仪并询问我的输入。为什么会发生这种情况，是否有任何方法可以使“＆gt;＆gt;”和扫描仪输入显示在一行上？

import java.util.Scanner;

import org.fusesource.jansi.AnsiConsole;


public class Test {
    public static void main(String[] args) {
        AnsiConsole.systemInstall();

        String name;
        Scanner scanner = new Scanner(System.in);

        String BLACK = "\u001B[0;30m";
        String RED = "\u001B[0;31m";
        String GREEN = "\u001B[0;32m";
        String YELLOW = "\u001B[0;33m";
        String BLUE = "\u001B[0;34m";
        String MAGENTA = "\u001B[0;35m";
        String CYAN = "\u001B[0;36m";
        String WHITE = "\u001B[0;37m";

        System.out.printf("Hello young lad! What is thy " + RED + "name " + WHITE + "you were given at birth?\n>> ");
        name = scanner.nextLine();
    }
}

此代码在注释掉AnsiConsole之后工作正常。

这是我打印出来的。

Hello young lad! What is thy [0;31mname [0;37myou were given at birth?
>> John

为什么我的printf语句末尾不打印“＆gt;＆gt;”？
