    Default PLEASE HELP

    Here is my error code:
    Please enter an animal: Now enter another: Exception in thread "main" java.util.NoSuchElementException: No line found
    at java.util.Scanner.nextLine(Scanner.java:
    at strings.main(strings.java:18

    And here is my code:
    import java.util.Scanner ;

    public class Strings {

    public static void main (String[] args) {


    Scanner input1 = new Scanner(System.in);
    Scanner input2 = new Scanner(System.in);
    Scanner input3 = new Scanner(System.in);

    //Get input from user

    System.out.print("Please enter an animal: ");
    String animal1 = input1.nextLine();

    System.out.print("Now enter another: ");
    String animal2 = input2.nextLine();

    System.out.print("One more, please: ");
    String animal3 = input3.nextLine();


    //First manipulation - Print the strings back out

    System.out.println("You entered " + animal1 + ", " + animal2 + ", and " + animal3 + ".") ;


    //Second manipulation - Print the length of the second string

    System.out.println("Your second animal is " + (animal2.length()) + " letters long.") ;


    //Third - Print the first string concatenated with the second

    System.out.println ("Your first and second animals were " + animal1 + ", and " + animal2);


    //Fourth - Print "true" if the first and second strings are the same, false if otherwise

    System.out.print("The first and second animal are the same: ");
    if (animal1==animal2) {
    System.out.println("true.");
    }
    else {
    System.out.println("false.");
    }


    //5 - Print out where the first character "c" appears in the first string, -1 if it doesnt

    System.out.println("Where is the letter C in the first animal? Look at letter number " + animal1.indexOf('c')) ;


    //6 - Print out where the third string appears in the second one, or -1

    System.out.println("Where does the third animal appear in the second one?: " + animal2.indexOf(animal3)) ;


    //7 - Print the second string in all capital letters

    System.out.println("YOUR SECOND ANIMAL IN ALL CAPITAL LETTERS IS: " + animal2.toUpperCase() + "!") ;


    //8 - Interpret the third string as an interger, add it to 10, print the result.

    Integer i = Integer.decode("123");
    System.out.println("If your third animal was a number, and I added ten to that number, it would be:" + i+10)


    } //end main
    } //end class

    I'm sure there's a lot of other errors as well, so please point them out! Thank you!

    When posting code, please use the highlight tags so we can actually read it.

    Also, please use a more descriptive post title. See the link in my signature on asking questions the smart way.

    Don't compare String with ==. Use the equals() method instead. Search this forum or google for good explanations of why.
