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
