add a element in array code example

Example 1: javascript pushing to an array

some_array = ["John", "Sally"];
some_array.push("Mike");

console.log(some_array); //output will be =>
["John", "Sally", "Mike"]

Example 2: javascript array push

let animals = ["dog","cat","tiger"];

animals.pop(); // ["dog","cat"]

animals.push("elephant"); // ["dog","cat","elephant"]

Example 3: java array add element

// A better solution would be to use an ArrayList which can grow as you need it. 
// The method ArrayList.toArray( T[] a ) 
// gives you back your array if you need it in this form.

List<String> where = new ArrayList<String>();
where.add(element);
where.add(element);

// If you need to convert it to a simple array...

String[] simpleArray = new String[ where.size() ];
where.toArray( simpleArray );

Example 4: java add element to existing array

//original array
String[] rgb = new String[] {"red", "green"};
//new array with one more length
String[] rgb2 = new String[rgb.length + 1];
//copy the old in the new array
System.arraycopy(rgb, 0, rgb2, 0, rgb.length);
//add element to new array
rgb2[rgb.length] = "blue";
//optional: set old array to new array
rgb = rgb2;
