package com.bethecoder.tutorials.guava.primitive_tests;

import com.google.common.primitives.Ints;

public class IntJoinTest {

  /**
   @param args
   */
  public static void main(String[] args) {
    String str = Ints.join("."123456);
    System.out.println(str);
    
    str = Ints.join("+"123456);
    System.out.println(str);
    
    str = Ints.join("-+-"123456);
    System.out.println(str);
  }
}
   

It gives the following output,
1.2.3.4.5.6
1+2+3+4+5+6
1-+-2-+-3-+-4-+-5-+-6
