Static String Static String Array

Static String Static String Array

Summary: By the end of this tutorial "Static String Static String Array", you will come to know creation of static string and static string array.

Like static variables, static strings and static string arrays are also common in Java coding. The same rules of static variables are followed. The following program creates one static string array names1 and one static string persons. The elements of static string array are put into static string and printed.

public class StringArrayManipulations
{
  static String names1[] = { "Jyostna", "Srinivas", "Pradeep", "Chandu" }; 
  public static String persons = "";
  public static void main(String args[])
  {
    for(String str : names1)
    {
      persons += str+ ", ";
    }
    System.out.println(persons);
  }
}
