Java Arrays in 5 Minutes

Why did the programmer quit his job? Because he didn't get arrays.

What is an array

Creating an array

int[] array = new int[10];
double[] array = {10.2, 15.4, 20.6, 25.8};
float[] array = new float[10];

Finding array length

int[] array = {22, 33, 44};
array.length

Java array utility class

import java.utils.Arrayspublic class ArrayTest{
public static void main(String args[]){
int[] array = {1,2,3};
Arrays.sort(array);
}
}
