Add Arraylist Java Code Example

Example 1: java insert into arraylist

ArrayList<Integer> str=new ArrayList<Integer>(); str.add(0); str.add(1);  // Result = [0, 1]      str.add(1, 11);  // Result = [0, 11, 1]

Example 2: insert element into arraylist java

ArrayList<String> arrayList = new ArrayList<>(); // Adds element at the back of the list arrayList.add("foo"); arrayList.add("bar"); // Result = ["foo", "bar"]  // Adds element at the specified index arrayList.add(1, "baz"); // Result = ["foo", "baz", "bar"]

Example 3: how to add to an arraylist java

import java.util.ArrayList; public class Details {     public static void main(String[] args) {          //ArrayList<String> Declaration         ArrayList<String> al= new ArrayList<String>();         //add method for String ArrayList         al.add("Ram");         al.add("Shyam");         al.add("CPS");         al.add("John");         al.add("Steve");         System.out.println("Elements of ArrayList of String Type: "+al);

Example 4: java arraylist add

//create ArrayList ArrayList<String> arrayList = new ArrayList<String>(); //add item to ArrayList arrayList.add("item"); //check if ArrayList contains item (returns boolean) System.out.println(arrayList.contains("item")); //remove item from ArrayList arrayList.remove("item");

Example 5: arraylist add method

public void add(int index, E element)	// no return value
