how to print String one after another in java

Question

I want to know that I want to print string one after another but in a particular time interval.

Everything is fine.

I want to know that when second string print override the first one and third override the second and so on..

How can I do this?

This is my code :

public class StringTest {

  public static void main(String args[]) {

    String arr[] = { "mahtab", "hussain", "yasir", "azmi", "saif" };

    int l = arr.length;

    for (int i = 0; i < arr.length; i++) {
      System.out.print(arr[i]);
      try {
        Thread.sleep(5 * 1000);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }
    }
  }
}

what does 'override the first one and third override the second' mean? — Chris K, Sep 10 '14 at 14:49
Where is the problem? What error are you getting? The current code should be printing those names one after the other with a 5 second delay. — f1sh, Sep 10 '14 at 14:49

What you need is escape sequences for you terminal. Console Java program do not directly manipulate screen. — talex, Sep 10 '14 at 14:52

You can simply do this with the carriage return \r.

System.out.print(arr[i]+"\r")

Use this

  for (int i = 0; i < arr.length; i++) {
  System.out.print(arr[i]);
  try {
    Thread.sleep(5 * 1000);
    for(int j=0;j<arr[i].length;j++){
        System.out.print("\b");
    }
  } catch (InterruptedException e) {
    e.printStackTrace();
  }

To remove the last character from the screen, you can use System.out.print("\b")
