integer array 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: java array declaration

int[] array = new int[/*size*/];
// Works for double, char, etc.

Example 3: java int array

int[] theNumbers = new int[5];

arr[0] = 4;
arr[1] = 8;
arr[2] = 15;
arr[3] = 16;
arr[4] = 23;
arr[5] = 42;

Example 4: java how to initialize an array

int[] arr = new int[10];	//Can hold 10 elements

Example 5: array in java

//method 1
int[] age = new int[3];
        age[0] = 1;
        age[1] = 3;
        age[2] = 6;

        for (int i=0; i < 3; i++)
            System.out.println(age[i]);

//method 2
        int[] num = {3,3,5};
        //int num[] = {3,3,5}; also works the same

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

Example 6: array declaration and initialization in java

int[] age = new int[5];
