如何在java中同一行打印字符串War Games样式一个字母

Question

using this code at the minute which I found on the net

 String welcome = "Would you like to play a game?";
 for (int i = 0; i < welcome.length(); i++) {
      System.out.println(welcome.charAt(i));

    }

Pretty basic stuff, but it prints out really quickly and line by line, how can i add a small pause, and print immediately after the previous character? So by the end it just says Would you like to play a game?

Im working in CMD, and Sublime text.

Thanks!

Answer 1

Use System.out.print instead of println. Use Thread.sleep to pause. Loop until the whole string is printed out.

String welcome = "Would you like to play a game?";
for (int i = 0; i < welcome.length(); i++) {
    System.out.print(welcome.charAt(i));
    Thread.sleep(1000L); // in milliseconds
}
System.out.println(); // start a new line

Thread.sleep throws InterruptedException. If this code goes in your main method, the easiest way to handle it (assuming you have no interest in canceling the thread by interrupting it) is to add throws InterruptedException to the main method declaration (the exception will not get thrown, you're just keeping the compiler happy).

Answer 2

Use System.out.print instead of System.out.println . To add a small delay the easiest thing is to use Thread.sleep .

Answer 3

 for (int i = 0; i < welcome.length(); i++) {
      System.out.print(welcome.charAt(i));
      Thread.sleep(100);
    }
