What happens when one string is appended to the end of another in Java?

Answer 1

This is called "concatenation", and pretty much just smashes the two Strings together. For example:

import java.util.*;

public class Example

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

System.out.println("Please enter a string: ");

String input = in.next();

System.out.println("Please enter another string: ");

String input2 = in.next();

String together = input + input2;

System.out.println("The strings concatenated yields: " + together);

}

}

OUTPUT:

Please enter a string:

Hello

Please enter another string:

Goodbye

The strings concatenated yields: HelloGoodbye

As well, you can use String.nextLine() to get more than one word per string:

import java.util.*;

public class Example

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

System.out.println("Please enter a string: ");

String input = in.nextLine();

System.out.println("Please enter another string: ");

String input2 = in.nextLine();

String together = input + input2;

System.out.println("The strings concatenated yields: " + together);

}

}
