I come from a php background and in php, there is an array_size() function which tells you how many elements in the array are used.

Is there a similar method for a String[] array? Thanks.

There is no such function or method in java, but there is a property which is useful in finding the length of array which is array.length

public class JavaArrayLengthExample


  public static void main(String[] args) {

      String[] intellipaat = {"java", "big data", "hadoop"};

      int arrayLength = intellipaat.length;

      System.out.format("The Java array length is %d", arrayLength);



Output would be -

The Java array length is 3
