Thread: Do while loop beak.

Hi, everyone! I have problem with my do while loop. I want to do, that user could break loop by him self. If I take int type variable it is okey, but when I try to do this with string or char it is does not working.
This is my code fragment:

import java.util.Scanner;
 
public class lab2 {
	public static void main(String args[]){
 
		String breakLoop;
		do{
		double alfa,beta, reiskinys1, neigiamas, teigiamas;
 
		Scanner input = new Scanner(System.in); // sukuriama bilioteka, kur saugomi ivesti duomenys
		System.out.println("Insert Alfa:");
		alfa = input.nextDouble();
		System.out.println("Insert Beta:");
		beta = input.nextDouble();
 
		reiskinys1 = 2*((Math.cos(0.5*(alfa+beta)))*Math.cos(0.5*(alfa-beta))); 
		System.out.println(reiskinys1);
 
		lab2 X = new lab2();
 
		if (reiskinys1 > 0){
			neigiamas=reiskinys1*(-1);
			System.out.println("Gautas skaicius: "+reiskinys1+" paverstas i neigiama: "+neigiamas);
			X.naujas(neigiamas);
		} else if (reiskinys1 < 0){
			teigiamas=reiskinys1*(-1);
			System.out.println("Gautas skaicius: "+reiskinys1+" paverstas i teigiama: "+teigiamas);
			X.naujas(teigiamas);
		} else {
			System.out.println("Gautas skaicius lygus 0, todel ir lieka toks pats: "+reiskinys1);
			X.naujas(reiskinys1);
		}
		System.out.println("IF YOU WANT TO BREAK PRESS N");
		breakLoop = input.next();
		} while(breakLoop!="N");
	}

Problem SOLVED.
