Java Program to Get a Character From the Given String

JavaCampus InterviewServer Side ProgrammingProgramming

In this article, we will understand how to get a character from the given string. Char is a datatype that contains an alphabets or an integer or an special character. String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”).

Below is a demonstration of the same −

Suppose our input is

Input string: Java Programming
Index: 11

The desired output would be

Result: m

Algorithm

Step 1 - START
Step 2 - Declare a string value namely input_string and a char value namely resultant_character.
Step 3 - Define the values.
Step 4 - Using the function string.charAt(), fetch the char value present at the specified position. Store the value in resultant_character.
Step 5 - Display the result
Step 6 - Stop

Example 1

Here, we bind all the operations together under the ‘main’ function.

public class CharacterAndString {
   public static void main(String[] args) {
      String string = "Java Programming";
      System.out.println("The string is defined as " +string);
      int index = 11;
      char resultant_character = string.charAt(index);
      System.out.println("\nA character from the string :" + string + " at index " + index + " is: " + resultant_character);
   }
}

Output

The string is defined as Java Programming

A character from the string :Java Programming at index 11 is: m

Example 2

Here, we encapsulate the operations into functions exhibiting object-oriented programming.

public class CharacterAndString {
   public static char get_chararacter(String string, int index) {
      return string.charAt(index);
   }
   public static void main(String[] args) {
      String string = "Java Programming";
      System.out.println("The string is defined as " +string);
      int index = 11;
      char resultant_character = get_chararacter(string, index);
      System.out.println("\nA character from the string :" + string + " at index " + index + " is: " + resultant_character);
   }
}

Output

The string is defined as Java Programming

A character from the string :Java Programming at index 11 is: m
