java scanner nextline code example

Example 1: java scanner string nextline after nextint

//The problem is with the input.nextInt() method - it only reads the int value. So when you continue reading with input.nextLine() you receive the "\n" Enter key. So to skip this you have to add the input.nextLine(). Hope this should be clear now.

//Try it like that:

System.out.print("Insert a number: ");
int number = input.nextInt();
input.nextLine(); // This line you have to add (It consumes the \n character)
System.out.print("Text1: ");
String text1 = input.nextLine();
System.out.print("Text2: ");
String text2 = input.nextLine();

Example 2: java scanner next()

String s = "Hello World! 3 + 3.0 = 6 ";

      // create a new scanner with the specified String Object
      Scanner scanner = new Scanner(s);

      // find the next token and print it
      System.out.println("" + scanner.next()); // "Hello"

      // find the next token and print it
      System.out.println("" + scanner.next()); // "World!"

      // close the scanner
      scanner.close();
