Program to print Characters of a string in Java

In this tutorial, we will discuss the concept of Program to print Characters of a string in Java

In this topic, we are going to learn how to display characters of a string in Java programming language using for, while and do-while loops.

Code to display characters of a string in Java

Program to print Characters of a string in Java — characters

Code to display characters of a string using for loop

In this program, we are briefing how to display characters of a string using for loop in Java language

Program 1

import java.util.Scanner;
public class PrintStringCharfor{
public static void main(String args[]){
String str;
    int i;
    Scanner sc=new Scanner(System.in);
    
    System.out.println("Please enter the String: ");
str=sc.nextLine();
for(i=0; i<str.length(); i++){
    	System.out.println("The charater of posotion "+i+": "+str.charAt(i));
}
}
}

When the above code is executed, it produces the following result

Please enter the string:
Java
The character of position 0 : J
The character of position 1 : a
The character of position 2 : v
The character of position 3 : a

Code to display characters of a string using while loop

In this program, we are briefing how to display characters of a string using while loop in Java language

Program 2

import java.util.Scanner;
public class PrintStringCharwhile{
public static void main(String args[]){
String str;
    int i;
    Scanner sc=new Scanner(System.in);
    
    System.out.println("Please enter the String: ");
str=sc.nextLine();
i=0;
while( i<str.length()){
    	System.out.println("The charaters of position: "+i+": "+str.charAt(i));
         i++;
}
}
}

When the above code is executed, it produces the following result

Please enter the string:
Language
The character of position 0 : L
The character of position 1 : a
The character of position 2 : n
The character of position 3 : g
The character of position 4 : u
The character of position 5 : a
The character of position 6 : g
The character of position 7 : e

Code to display characters of a string using do-while loop

In this program, we are briefing how to display characters of a string using do-while loop in Java language

Program 3

import java.util.Scanner;
public class PrintStringCharDowhile{
public static void main(String args[]){
String str;
    int i;
    Scanner sc=new Scanner(System.in);
    
    System.out.println("Please enter the String: ");
str=sc.nextLine();
i=0;
do{
    	System.out.println("The charaters of position "+i+": "+str.charAt(i));
         i++;
}while(i<str.length());
}
}

When the above code is executed, it produces the following result

Please enter the string:

DoWhile
The character of position 0 : D
The character of position 1 : o
The character of position 2 : W
The character of position 3 : h
The character of position 4 : i
The character of position 5 : l
The character of position 6 : e
