User input numbers not adding together

Question

I\'m trying to write a program that reads an integer from the user (through the keyboard), adds 100 to it and displays the result. All I can do is get them to concatenate like 2

Answer 1

You are adding the wrong variable. Use this instead:

System.out.println(" Your value + 100 is " + ( 100 + number));

Answer 2

Text is the String, number an int, thus use:

System.out.println(" Your value + 100 is " + ( 100 + number));

For Strings + concatenates.

Answer 3

int number = Integer.parseInt(text) + 100;

 System.out.println(" Your value + 100 is " + ( number));

or

System.out.println(" Your value + 100 is " + ( 100 + number));

For a string "+" works to concatenate , i.e append the string together :)
