Tutorial : Java String

A string is an ordered sequence of symbols. Sting class is included in java.lang package. So each class in Java, can use String class without importing any package. The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.

Java String Class/Java String API
Java String class or Java String API is under package java.lang. String class provides various methods to play with strings for example: length(), charAt(int index), substring(int begin, int end), StringTokenizer (it’s a class), toUpperCase(), equals()…. and some others.

Java String Array
We may also declare arrays of type string. String Array can store strings in it.

Example:

• Code:
  
  String[] str_array = new String[2];
  str_array[0] = "Java String";
  str_array[1] = "Java String Array";
  
  System.out.println("Index 0: " + str_array[0]);
  System.out.println("Index 1: " + str_array[1]);

Output:
Index 0: Java String
Index 1: Java String Array

Arrays in Java start from index 0. In the above example, first we declared an array named str_array of size 2. It means it will have index 0 and 1. We added some text in arrays index 0 and 1 and then displayed on the console...
