One dimensional array shows how to declare initialize and display an array.

// Declaration of allocating memory to an array

int iarr[] = new int[3];

// Initializing elements

iarr[0] = 1;

iarr[1] = 2;

iarr[2] = 3;

//Display array elements

System.out.println(iarr[0]);

System.out.println(iarr[1]);

System.out.println(iarr[2]);

// Or Use for loop to display elements

for (int i = 0; i < iarr.length; i = i + 1)

{

System.out.print(iarr[i]);

System.out.print(" ");

}
