Arrays in java language
Download as PPTX, PDF0 likes1,083 views
An array in Java is a group of variables of the same type that can store multiple values. Arrays are created using syntax like int[] arrayName = new int[size]; and values are assigned to elements in the array using indexes that start from 0. For example, an int array of size 4 could be initialized with values through arrayName[0]=1; arrayName[1]=22; etc. The document also provides a short Java program example to demonstrate printing the values of an int array.

![When array has 4 values like following array
int[] d = new int[4];
You can set te values of the int array starting
by the index of array with 0 like in the following
example
d[0]=1;
d[1]=22;
d[2]=23;
d[3]=12;
These are the values of int[] array which has
range of array upto 10 values](https://image.slidesharecdn.com/arraysinjavalanguage-150527154734-lva1-app6891/85/Arrays-in-java-language-5-320.jpg)
![Here is the small java program which prints an int array
public class Arraylist
{
public static void main(String args[])
{
int[] c = new int[3];
//setting the values of the array
c[0]=1;
c[1]=12;
c[2]=33;
//print the first values of the arary
System.out.println(c[0]);
System.out.println(c[1]);
System.out.println(c[2]);
