Issue concerning nextLine() in java

[kcchi]

                while(temp <= numOfPlayers){

                    System.out.print(userNamePrompt.replace(NUMBER, "#" + temp));

 -->               String name = console.nextLine();

                    players[temp-1].setName(name);

                    temp++;

                }

 

numOfPlayers = 2

NUMBER = "%NUMBER"

userNamePrompt = "Name of racer %NUMBER"

console = Scanner(System.in)

temp = 1

players  = arrays of objects of type Player

 

The output I want is:

 

Name of racer #1: , then waits for my input

Name of racer #2: , then waits for my input again

 

What I get with nextLine() is:

 

Name of racer #1: Name of racer #2: , then waits for my input (only takes 1 input, not 2)

 

Basically it goes through the while loop twice before asking me for an input. I know it works with the next() method but the problem is when the user inputs a name with a space in between, i.e. Sponge Bob, which would put Sponge in name 1 and Bob in name 2. Why doesn't nextLine() work in this case and how do I make it so it takes Sponge Bob as one name? Thanks guys

• Your use of a while loop when you want a temporary variable just for the loop, have a condition to break it and something to increment for that condition is pretty bad. Use a for-loop for that since it covers all those bases.
• The whole having a prompt is nice, but replacing of the string isn't really necessary, especially when you only prompt once.
• The reason you're printing on a single line is because you're using the print() function rather than the println() function, the difference being that println() appends the newline character at the end.

Next time can you paste code using the code tags with exactly what you have in your editor. It makes it a hell of a lot easier to read and debug.

 

My implementation:

public static void main(String[] args) {	// Set number of players	int numPlayers = 2;	// Create array for player names	String playerNames[] = new String[numPlayers];	// capture input source	Scanner input = new Scanner(System.in);	// For player slots...	for (int i = 0; i < numPlayers; i++) {		// Prompt for name		System.out.println("Enter the name of Player " + Integer.toString(i + 1) + ":");		// Store name		playerNames[i] = input.nextLine();	}	// Output names	System.out.println("Player names:");	// For each player	for (String s:playerNames) {		// Print out name		System.out.println(s);	}}
