array size in java code example

Example 1: .length array java

/**
* An Example to get the Array Length is Java
*/
public class ArrayLengthJava {
public static void main(String[] args) {
String[] myArray = { "I", "Love", "Music" };
int arrayLength = myArray.length; //array length attribute
System.out.println("The length of the array is: " + arrayLength);
}
}

Example 2: define an array of size n in java

int[] myIntArray = new int[3];
int[] myIntArray = {1, 2, 3};
int[] myIntArray = new int[]{1, 2, 3};

// Since Java 8. Doc of IntStream: https://docs.oracle.com/javase/8/docs/api/java/util/stream/IntStream.html

int [] myIntArray = IntStream.range(0, 100).toArray(); // From 0 to 99
int [] myIntArray = IntStream.rangeClosed(0, 100).toArray(); // From 0 to 100
int [] myIntArray = IntStream.of(12,25,36,85,28,96,47).toArray(); // The order is preserved.
int [] myIntArray = IntStream.of(12,25,36,85,28,96,47).sorted().toArray(); // Sort

Example 3: find length of array java

Int[] array = {1,2,3};
int lengthOfArray = array.length; /** Finding the length of the array and storing it */
System.out.println(String.valueOf(lengthOfArray)); /** Should print out 3, String.value Of() is optional as printLn does this automatically. */

Example 4: how to find length of array in java

let coolCars = ['ford', 'chevy'];
//to find length, use the array's built in method
let length = coolCars.length;
//length == 2.

Example 5: length of array in java

arr.length;

Example 6: set array length java

int[] num = new int[5];
