How to accept array input and print in Java using do-while loop

In this article, we will discuss the concept of How to accept array input and print in Java using do-while loop

In this post, we are going to learn how to write a program to read array input and print given elements in an array using do-while loop in Java language

Code to read input and print of  array elements

Code to take input and print integer of an array using do-while loop

In this code, we are going to learn how to read integer array input given by user and print the them using do-while loop in Java language

Program 1

//Java program to read and print in an one dim array using dowhile
//Using do-whuile loop
import java.util.Scanner;
class Array_Sin_Dim_Int_Dowhile1{
public static void main (String args[]){
  Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input for array length
int len=scan.nextInt();
//Reading the user input for array length
int arr[]=new int[len]; 
//diclaration and creation of a array

System.out.println("Enter the array elements");
//Ask input from the user for array elements
int i=0;
do{
arr[i]=scan.nextInt();
//Reading input from the user for array elements 
 i++;
}while(i<len);
//reading every array element
System.out.println("\narray elements are:");
i=0; 
do{
System.out.println(arr[i]); 
 i++;
}while(i<len);
  //display every array element
}
}

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

 

Program 2

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Sin_Dim_Int_Dowhile2{
public static void main (String args[]){
  Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
int len=scan.nextInt();
int arr[]=new int[len]; //diclaration and creation

System.out.println("Enter the array elements");
int i=0;
do{
System.out.print("[arr["+i+"]:"); 
arr[i]=scan.nextInt(); 
 i++;
}while(i<len);
System.out.println("\narray elements are:");
i=0;
do{
System.out.println("[arr["+i+"]:"+arr[i]); 
 i++;
}while(i<len);
//display every array element
}
}

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

 

 

Code to take input and print string of an array using do-while loop

In this code, we are going to learn how to read string array input given by user and print the them using do-while loop in Java language

Program 2

//Java program to read and print String an array using while
import java.util.Scanner;
class Array_Sin_Dim_String_DoWhile1{
public static void main (String args[]){
  Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len]; 
//diclaration and creation of an array

System.out.println("Enter the "+len+" String");
int i=0;
do{
arr[i]=scan.next(); 
//Reding the input from the user
 i++;
}while(i<len);
System.out.println("\nEntered string are:");

int j=0; 
do{
System.out.println(arr[j]);
j++;
//display every array element
}while(j<len);

 
}
}

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

 

Program 2

//Java program to read and print String a array using do-while
import java.util.Scanner;
class Array_Sin_Dim_String_DoWhile_2{
public static void main (String args[]){
  Scanner scan=new Scanner(System.in);
//create a scanner instance for receives input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int len=scan.nextInt();
//Reading the input from the user
String arr[]=new String[len]; 
//diclaration and creation of an array

System.out.println("Enter the "+len+" String");
int i=0;
do{
  System.out.print("[arr["+i+"]:");
arr[i]=scan.next(); 
//Reding the input from the user
 i++;
}while(i<len);
System.out.println("\nEntered string are:");
int j=0; 
do{
System.out.println("[arr["+j+"]:"+arr[j]);
 j++;
}while(j<len);//display every array element
}
}

Code to take input and print character of an array using do-while loop

In this code, we are going to learn how to read character array input given by user and print the them using do-while loop in Java language

Program 2

//Read and print character of an array using do-while loop
import java.util.Scanner;
class Arr_One_Dim_Char_DoWhile1{
public static void main (String args[]){
  Scanner sc=new Scanner(System.in);
//create a scanner object for Taking input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int length=sc.nextInt();
//Reading the input from the user for array length
char arr[]=new char[length]; 
//diclaration and creation of char array

System.out.println("Enter the "+length+" Characters");
int i=0;
do{
arr[i]=sc.next().charAt(0); 
//Reding the input(characters) from the user
 i++;
}while(i<length);
System.out.println("\nEntered characters are:");
int j=0; 
do{
System.out.println(arr[j]); 
 j++;
}while(j<length);
//display all entered characters
}
}

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

 

Program 2

//Read and print character of an array using do-while loop
import java.util.Scanner;
class Arr_One_Dim_Char_DoWhile2{
public static void main (String args[]){
  Scanner sc=new Scanner(System.in);
//create a scanner object for Taking input
// from the user - input from keyboard
System.out.print("Enter the Array length: ");
//Ask input from the user for array length
int length=sc.nextInt();
//Reading the input from the user
char arr[]=new char[length]; 
//diclaration and creation of an array

System.out.println("Enter the "+length+" Characters");
int i=0; 
do{
  System.out.print("[arr["+i+"]:");
arr[i]=sc.next().charAt(0); 
//Reding the input(characters) from the user
 i++;
}while(i<length);
System.out.println("\nEntered characters are:");
int j=0; 
do{
  System.out.print("[arr["+j+"]:");
System.out.println(arr[j]); 
 j++;
}while(j<length);
//display all entered characters
}
}
