Java program to read and print elements of one dim array

Java program to read and print elements of one dim array

In this tutorial, we will discuss the concept of Java program to read and print elements of one dimensional array

In this topic, we are going to learn how to read and print elements of a one dimensional array in Java programming language  using loops

 

In this blog, We have already discuss that “What is an array”, type of arrays and how to access it

Arrays are the special type of variables to store Multiple type of values(int, string,char, etc)under the same name in the continuous memory location. we can be easily accessed using the indices(indexes)

Here,

• e1,e2,e3,e4 and e5 represent the elements of the array
• 0,1,2,3,4 represent the index of the array which is used to access the array elements
• 1,2,3,4,5 represent the length of the array

Code to read and print elements of one dim array

Read and print elements Using for loop

In this program, we are briefing input elements of an array and then print them using for loop in Java language

Program 1

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Single_Dim{
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]; //declaration and creation i dim array

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

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

 

 

Program 2

In this program, we are briefing input elements of an array and then print them using for loop in Java language

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Single_Dim1{
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]; //declaration and creation 1 dim array

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

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

 

Read and print elements Using while loop

In this program, we are briefing input elements of an array and then print them using while loop in Java language

Program 1

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Single_Dimwhile{
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]; //declaration and creation i dim array

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

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

 

Program 2

In this program, we are briefing input elements of an array and then print them using while loop in Java language

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Single_Dimwhile1{
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]; //declaration and creation 1 dim array

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

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

Read and print elements Using do-while loop

In this program, we are briefing input elements of an array and then print them using do-while loop in Java language

Program 1

//Java program to read and print elements a one dimensional array
import java.util.Scanner;
class Array_Single_DimDowhile{
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]; //declaration and creation 1 dim array

System.out.println("Enter the array elements");
int i=0;
do{
arr[i]=scan.nextInt(); 
 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

System.out.print("Enter the Array length: ");
int len=scan.nextInt();
int arr[]=new int[len]; //declaration and creation 1 dim array

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
}
}
