creating a method for texts

Expand Post »

I need to creat a method something like... when the user inputs

test1
test2 haha

test3
end

and display that should contain exact same one as above except "end":
test1
test2 haha

test3

so the "end" is the keyword to finish the inputing...

Java Syntax (Toggle Plain Text)
                    String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);
 
		while(!s.equals("end")){
			s = keyboard.nextLine();
			s1 += s + "\n"; 
 
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);
                    String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);
		
		while(!s.equals("end")){
			s = keyboard.nextLine();
			s1 += s + "\n"; 
		
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);

oh I've just figured out. however, i see see the "end". how do i remove it?

That is not what enuff4life has asked. Try this:

Java Syntax (Toggle Plain Text)
                    String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);
 
		while(!s.equals("end")){
			s = keyboard.nextLine();
 
                       if (!s.equals("end")) {
                             s1 += s + "\n"; 
                       }
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);
                    String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);
		
		while(!s.equals("end")){
			s = keyboard.nextLine();

                       if (!s.equals("end")) {
                             s1 += s + "\n"; 
                       }
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);

Or keep the while-loop as it is and use the methods:
String.indexOf()
and
String.subString()

Java Syntax (Toggle Plain Text)
int index = s1.indexOf("end");
System.out.println(s1.subString(0,index));
int index = s1.indexOf("end");
System.out.println(s1.subString(0,index));

Link for the String class.

or this way:

Java Syntax (Toggle Plain Text)
              String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);

                        s = keyboard.nextLine();
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);
              String s = new String("");
		String s1 = new String("");
		System.out.println("enter String : ");
		Scanner keyboard = new Scanner(System.in);
		s = keyboard.nextLine();
		while(!s.equals("end")){
			s1 += s + "\n"; 
                        s = keyboard.nextLine();
		}
		System.out.println("you've typed: \n");
		System.out.println(s1);
