    Question java Conversion & Casting

    What will be the output when you compile and run the program? Explain your answers.

    class Example{
    public static void main(String args[]){
    byte b1=10,b2=20,b3;
    b3=b1+b2; //Line 1
    b3=b1+1; //Line 2
    b3=b1*2; //Line 3
    short s1=10,s2=20,s3;
    s3=s1+s2; //Line 4
    s3=s1+1; //Line 5
    s3=s*1; //Line 6
    int x1=10,x2=20,x3;
    x3=x1+x2; //Line 7
    x3=b1+b2; //Line 8
    x3=b1+1; //Line 9
    x3=b1*2; //Line 10
    x3=s1+s2; //Line 11

    What do you think?
    The code needs lots of print statements to have output. Try adding print statements so you can see what the values are for each statement and variable.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Please add System.out.println after each assignment ie
    b3=b1+b2; //Line 1
    System.out.println( " Value of b3 now "+b3);
    by the way I noticed following compilation error with your program ...did you get this ?
    incompatible types: possible lossy conversion from int to byte
    b3=b1+b2; //Line 1
