Program to print characters in a string using Java

Program to print characters in a string using Java

In this article, we will discuss the concept of Program to print characters in a string using Java

In this post, we are going to learn how to write a program to  separate characters of a given string  in Java language

Code to separate  characters of a string

Code to separate characters of a string using for loop – #1

In this code, we are going to learn how to separate individual characters in the given string   using for loop in Java language

Program 1

public class PrintStringCharfor1{
  //class with class name
public static void main(String args[]){
  //main method
String str="String";//declare a string variale
  int i;//declare a integer variable
for(i=0; i<str.length(); i++){
     System.out.println("The charaters of posotion: "+i+": "+str.charAt(i));
    //display the characters of a string
}
}
}

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

The characters of a position 0: S
The characters of a position 1: t
The characters of a position 2: r
The characters of a position 3: i
The characters of a position 4: n
The characters of a position 5: g

 

Code to separate characters of a string using for loop – #2

In this code, we are going to learn how to separate individual characters in the given string   using for loop in Java language

Program 2

import java.util.Scanner;
public class PrintStringCharfor{
  //class with class name
public static void main(String args[]){
  //main method
String str;//declare a string variale
  int i;//declare a integer variable
  Scanner sc=new Scanner(System.in);
  //scanner object for user input
  System.out.println("Please enter your String: ");
str=sc.nextLine();
for(i=0; i<str.length(); i++){
     System.out.println("The charaters of position: "+i+": "+str.charAt(i));
    //display the characters of a string
}
}
}

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

Please enter your string
MyCode
The characters of a position 0: M
The characters of a position 1: y
The characters of a position 2: C
The characters of a position 3: o
The characters of a position 4: d
The characters of a position 5: e

 

Code to separate characters of a string using while loop – #1

In this code, we are going to learn how to separate individual characters in the given string   using while loop in Java language

Program 1

public class PrintStringCharwhile1{
  //class with class name
public static void main(String args[]){
  //main method
String str="Character";//declare a string variale
  int i;//declare a integer variable
  i=0;
while(i<str.length()){
     System.out.println("The charaters of posotion: "+i+": "+str.charAt(i));
    //display the characters of a string
     i++;
}
}
}

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

The characters of a position 0: C
The characters of a position 1: h
The characters of a position 2: a
The characters of a position 3: r
The characters of a position 4: a
The characters of a position 5: c
The characters of a position 6: t
The characters of a position 7: e
The characters of a position 8: r

 

Code to separate characters of a string using while loop – #2

In this code, we are going to learn how to separate individual characters in the given string   using while loop in Java language

Program 2

import java.util.Scanner;
public class PrintStringCharwhile{
public static void main(String args[]){
String str;//declare a string variable
  int i;//declare a integer variable
  Scanner sc=new Scanner(System.in);
  
  System.out.println("Please enter the String: ");
str=sc.nextLine();//Take input from the user
i=0;
while( i<str.length()){
     System.out.println("The charaters of index: "+i+": "+str.charAt(i));
     i++;//display character of a string
}
}
}

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

Please enter a string
CodeJava

The characters of a position 0: C
The characters of a position 1: o
The characters of a position 2: d
The characters of a position 3: e
The characters of a position 4: J
The characters of a position 5: a
The characters of a position 6: v
The characters of a position 7: a

 

Code to separate characters of a string using do-while loop – #1

In this code, we are going to learn how to separate individual characters in the given string   using do-while loop in Java language

Program 1

public class PrintStringChardowhile1{
  //class with class name
public static void main(String args[]){
  //main method
String str="Variable";//declare a string variale
  int i;//declare a integer variable
  i=0;
do{
     System.out.println("The charaters of posotion: "+i+": "+str.charAt(i));
    //display the characters of a string
     i++;
}while(i<str.length());
}
}

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

The characters of a position 0: V
The characters of a position 1: a
The characters of a position 2: r
The characters of a position 3: i
The characters of a position 4: a
The characters of a position 5: b
The characters of a position 6: l
The characters of a position 7: e

Code to separate characters of a string using do-while loop – #2

In this code, we are going to learn how to separate individual characters in the given string   using do-while loop in Java language

Program 2

import java.util.Scanner;
public class PrintStringCharDowhile{
public static void main(String args[]){
String str;//Declare string variable
  int i;//Declare character variable
  Scanner sc=new Scanner(System.in);
  //Scanner object for get user input
  System.out.println("Please enter the String: ");
str=sc.nextLine();//Take input from user
i=0;
do{
     System.out.println("The charaters of index: "+i+": "+str.charAt(i));
     i++;//Display characters of a string
}while(i<str.length());
}
}

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

Please enter a string
MyStr
The characters of a position 0: M
The characters of a position 1: y
The characters of a position 2: S
The characters of a position 3: t
The characters of a position 4: r
