How can you initialize an array in Java?

Answer 1

If you refering to Object then String[] something=new String[2]; Here you have to remember that something only allocated space for 2 String object but it did not created them yet. By default Objects are intantiated to null so if you try to print the content of an array System.out.println(something[0]);//print null System.out.println(something[0].toLowerCase()); Throws NullPointerException Couple other ways to create Arrays In java String[] something=new String[]{"Me","You"}; String[] something={"Me", "You"};

Answer 2

// Declaring an array

int[] a;

// Instantiating an array

a = new int[10];

// Initializing an array

for(int i = 0; i < a.length; ++i) {

a[i] = 0;

}
