    Default Issue with output format

    Hello,

    I am a beginner in java and I want to output a line as follow :

    "your number is (x,y) and is on the third line "

    x and y are the user input and if I put a number for example 1 as x and 2 as y it add instead of putting a comma between the two numbers .

    my code is as follow :

    system.out.print("your number is " + (x + y)+" is on the third line ");

    I hope someone can help resolve this issue

    Thanks

    '2 + 3' is an int expression - it can be evaluated as 5. '"your number is " + 5' is evaluated as a string concatenation because the 5 is 'promoted' to a string:
    Conversions and Promotions
    See section 5.1.6
    Think of a way of writing your string concatenation so that there aren't two int values either side of a '+'.
