create array code example
Example 1: java array declaration
int[] array = new int[/*size*/];
// Works for double, char, etc.
Example 2: 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 3: java how to initialize an array
int[] arr = new int[10]; //Can hold 10 elements
Example 4: how to declare an array in java
An array is an ordered collection of elements of the same type, identified by a pair of square brackets [].
To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
int[] marks; // Declare an int array named marks
// marks contains a special value called null.
int marks[]; // Same as above, but the above syntax recommended
marks = new int[5]; // Allocate 5 elements via the "new" operator
// Declare and allocate a 20-element array in one statement via "new" operator
int[] factors = new int[20];
// Declare, allocate a 6-element array thru initialization
int[] numbers = {11, 22, 33, 44, 55, 66}; // size of array deduced from the number of items
Example 5: how to get element of an array in javascript
var value = [a,b,c,d];
var value_b = value[1];
Example 6: 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]);
}
}
