how to add in array in java code example
Example 1: how to add elements in string array in java
Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here). Instead, use a List : ArrayList<String> mylist = new ArrayList<String>(); mylist. add(mystring);
Example 2: java array add element
List<String> where = new ArrayList<String>();
where.add(element);
where.add(element);
String[] simpleArray = new String[ where.size() ];
where.toArray( simpleArray );
Example 3: java add element to existing array
String[] rgb = new String[] {"red", "green"};
String[] rgb2 = new String[rgb.length + 1];
System.arraycopy(rgb, 0, rgb2, 0, rgb.length);
rgb2[rgb.length] = "blue";
rgb = rgb2;
Example 4: how to add a number to an array in java
List<Integer> myList = new ArrayList<Integer>();
myList.add(5);
myList.add(7);
Example 5: how to add to an array
var ar = ['one', 'two', 'three'];
ar[3] = 'four';
