我有一个简单的 main 方法,其中包含数十个“System.out.print”,如下所示:

public class StudentTester 
{ 
    public static void main() 
    { 
 
        System.out.print('\f'); 
 
        System.out.println("1"); 
        System.out.println("2"); 
        System.out.println("3"); 
        System.out.println("4"); 
        System.out.println("5"); 
        System.out.println("6"); 
        System.out.println("7"); 
        System.out.println("8"); 
        System.out.println("9"); 
        System.out.println("10"); 
        System.out.println("11"); 
        System.out.println("12"); 
        System.out.println("13"); 
        System.out.println("14"); 
        System.out.println("15"); 
        System.out.println("16"); 
        System.out.println("17"); 
        System.out.println("18"); 
        System.out.println("19"); 
        System.out.println("20"); 
        System.out.println("21"); 
        System.out.println("22"); 
        System.out.println("23"); 
        System.out.println("24"); 
        System.out.println("25"); 
        System.out.println("26"); 
        System.out.println("27"); 
        System.out.println("28"); 
        System.out.println("29"); 
        System.out.println("30"); 
        System.out.println("31"); 
        System.out.println("32"); 
        System.out.println("33"); 
        System.out.println("34"); 
        System.out.println("35"); 
        System.out.println("36"); 
        System.out.println("37"); 
        System.out.println("38"); 
        System.out.println("39"); 
        System.out.println("40"); 
        System.out.println("41"); 
        System.out.println("42"); 
        System.out.println("43"); 
        System.out.println("44"); 
        System.out.println("45"); 
        System.out.println("46"); 
        System.out.println("47"); 
        System.out.println("48"); 
        System.out.println("49"); 
        System.out.println("50"); 
        System.out.println("51"); 
        System.out.println("52"); 
        System.out.println("53"); 
        System.out.println("54"); 
        System.out.println("55"); 
        System.out.println("56"); 
        System.out.println("57"); 
        System.out.println("58"); 
        System.out.println("59");         
        System.out.println("60"); 
        System.out.println("61"); 
        System.out.println("62"); 
        System.out.println("63"); 
        System.out.println("64"); 
        System.out.println("65"); 
        System.out.println("66"); 
        System.out.println("67"); 
        System.out.println("68"); 
        System.out.println("69"); 
        System.out.println("70"); 
 
} 

但是,当我运行该程序时,BlueJ 仅显示 24-70。

为什么?

请您参考如下方法:

在 BlueJ 终端窗口中,转到选项并打开无限缓冲。这将解决您的问题。您还可以在方法调用时启用清屏,使每个程序在清屏上运行。
