Question

Does anyone know of a Java compiler that allows you to compile line by line?

I am a Java newbie and I was hoping someone might know of compiler that functions line by line so I could get a better understanding of the results of each line. It would be great if someone knew of a compiler that also showed the changing results of values on the side too.

Thanks

Answer 1

u can print the values out by System.out.println();

for instance print the values in functions or in each line and specify the line number so u can see how compiler compiles the program.

Answer 2

u can do that using a normal compiler by putting a break point at every line

and u can put the variables in the watch window to check their value every break point

this is in Visual studio IDE" integrated Development environment"

they have a visual Java# compiler

Answer 3

use the command line tool "javap.exe" to see what is going on in your code. this file is in your jdk/bin folder. usage is

$> javap -c yourclassfile

this is not a line by line compiler but you will see what does Java do with your code.

Answer 4

Use Eclipse IDE. That's free...and easy to use...
