Write a Java program to get the character at the given index within the String.

we can learn to get the character at the given index within the String

Approach Steps 🤔

Take given original string
Print original string for reference
use the charAt() method to find out a character at a given index i.e original.charAt(1);
hold it by int type
while display time typecast int to char
print out the result on the console.

Code bit :

Practice Code in LeetCode PlayGround 🥇🥇🥇🥇

Source code :

public class MainClass {

public static void main(String[] args) throws IOException {

// take a Given string

String original = "Java Code Practice";

// Print original string for reference

System.out.println( "Given original string :--"+ original+"\n");

// chatAt method : it is used for find out character at given index

// hold it by int type

int givenIndex = original.charAt(1);

// while display time type cast to char

// Print the character at given index

System.out.println( "the character at zero index :-- "+(char)givenIndex);

}

Result :

Learnt from this Code Bit :

charAt() method: this method is used for getting a character at a given index from the original string. for the above example gave an index at 1 in charAt(1) method so got the result "a".
One more thing "\n" used for the next line
type casting is done int to char so got it from the above code bit.

Thank you!
