Java String join example

String’s join method can be used to join various String by the delimiter. It is introduced in java 8.

For example: We need to join various Strings by “,”. You can use join method as

String.join(",","java","blog","tutorials");
// Output
"java,blog,tutorial"

There are two overloaded variants of String’s join method:

public static String join(CharSequence delimiter, CharSequence... elements)  
and  
public static String join(CharSequence delimiter, Iterable elements)

String join example:

package org.arpit.java2blog;

public class StringJoinExample {

 public static void main(String[] args) {

  System.out.println(String.join(",","java","blog","tutorials"));
  System.out.println(String.join("-","java","blog","tutorials"));
 }

}
