declaring arrays code example

Example 1: how to create an array in java

int[] array1 = new int[5]; //int array length 5
String[] array2 = new String[5] //String array length 5
double[] array3 = new double[5] // Double array length 5

Example 2: Arrays in java

// Accessing array elements using for loop
public class AccessingArrayElements
{
   public static void main(String[] args)
   {
      int[] arrNum = {25, 23, 15, 20, 24};
      for(int a = 0; a < arrNum.length; a++)
      {
         System.out.println(arrNum[a]);
      }
   }
}

Example 3: arrays in java

int[] arr;			// Declaration dataType can int, float etc.
arr = new int[N];	// Allocation N = 0 to 2,147,483,647.
