Program to print array elements in Java

Program to print array elements in Java

In this tutorial, we will discuss the concept of program to print array elements in Java

In this topic, we are going to learn how to print integer array elements in Java programming language  using for, while and do-while loops.

 

In this blog, We have already discuss that “What is an array“, type of arrays and how to access it(one dim, two dim and three dim arrays)

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 string elements of the array
• 0,1,2,3 and 4 represent the index of the array which is used to access the array elements
• 1,2,3,4 and 5 represent the length of the array

Code to  print array elements of one dim array

Program to Display array in Java using for loop

In this program, we are briefing how to print  integer elements  of an array using for loop in Java language

Program 1

//Display integer of an array using for loop

class Disp_Array_ele{
public static void main (String args[]){
int arr[]=new int[]{2,4,6,8,10,12}; 
//diclaration and initialization of an array

System.out.println("Display elements of given array");

//for loop use to displays the elements by incrementing value of i
for(int i=0; i<arr.length; i++){
System.out.print(arr[i]+" ");

}
}
}

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

Display elements of given array
2,4,6,8,10,12

 

Program to Display array in Java using while loop

In this program, we are briefing how to print integer array elements of an array using while loop in Java language

Program 2

//Display integer of an array using while loop

class Disp_Array_ele1{
public static void main (String args[]){
int arr[]=new int[]{21,24,64,68,10,12}; 
//diclaration and initialization of an array

System.out.println("Display elements of given array");

//while loop use to displays the elements by incrementing value of i
int i=0; 
while(i<arr.length){
System.out.print(arr[i]+" ");
 i++;
}
}
}

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

Display elements of given array
21,24,64,68,10,12

 

Program to Display array in Java using do-while loop

In this program, we are briefing how to  print integer array elements using do-while loop in Java language

Program 3

//Display integer of an array using do-while loop

class Disp_Array_ele2{
public static void main (String args[]){
int arr[]=new int[]{210,241,264,268,210,212}; 
//diclaration and initialization of an array

System.out.println("Display elements of given array");

//do-while loop use to displays the elements by incrementing value of i
int i=0; 
do{
System.out.print(arr[i]+" ");
 i++;
}while(i<arr.length);
}
}

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

Display elements of given array
210,241,264,268,210,212
