The toString() method of CopyOnWriteArrayList returns the string representation of the list.
Syntax:
public String toString()
Parameters: The function does not accepts any parameter.
Return Value: The function returns the string representation of the list.
Below programs illustrate the above function:
Program 1:
// Java Program to illustrate the CopyOnWriteArrayList// toString() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*; public class GFG { public static void main(String[] args) { // create object of CopyOnWriteArrayList CopyOnWriteArrayList<Integer> ArrLis = new CopyOnWriteArrayList<Integer>(); // Add elements ArrLis.add(32); ArrLis.add(67); ArrLis.add(98); ArrLis.add(100); // print CopyOnWriteArrayList System.out.println("CopyOnWriteArrayList: " + ArrLis); System.out.println("ArrLis converted to string: " + ArrLis.toString()); }} |
Output:
CopyOnWriteArrayList: [32, 67, 98, 100] ArrLis converted to string: [32, 67, 98, 100]
Program 2:
// Java Program to illustrate the CopyOnWriteArrayList// toString()() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*; public class GFG { public static void main(String[] args) { // create object of CopyOnWriteArrayList CopyOnWriteArrayList<String> ArrLis = new CopyOnWriteArrayList<String>(); // Add elements ArrLis.add("gopal"); ArrLis.add("gfg"); ArrLis.add("jgec"); ArrLis.add("sudo"); // print CopyOnWriteArrayList System.out.println("CopyOnWriteArrayList: " + ArrLis); System.out.println("ArrLis converted to string: " + ArrLis.toString()); }} |
Output:
CopyOnWriteArrayList: [gopal, gfg, jgec, sudo] ArrLis converted to string: [gopal, gfg, jgec, sudo]
