How to break a cycle with a String?

Question

I want to give user a possibility to stop inputing new lines in my String array by entering the word "end". I checked out - it really inputs 'end' before the if statement, but for some reason this doesn't break the while cycle:

Scanner scan = new Scanner(System.in);           
String[] str = new String[50];                    
int j=0;
int f = 0;                           
System.out.println("Input 'end' to see your previous input!");
while(f != -1)
{

the input goes well, but the if statement doesn't work completely

 String choice = scan.nextLine();   
             if(choice == "end")               
             {
                 f = -1;              
             }
             else
             {
                 str[j] = choice;
                 j++;
             }
       }

Answer 1

Use

choice.equals("end") instead of ==
