Hi,

I am not getting the output for this program. It is compiling but did not get any output.


class test {
public static void main(String args[]) {
if(args.length > 0)
System.out.println(args.length);
}
}

It will only print something if you give it an argument -- i.e.,

java test Hello

will print "1". The argument list includes neither "java" nor the name of the class.

hi

the part "String[] args" actually refers to command-line arguments. so, if you execute it without one, the value of args.length() is zero. since you have asked the code to print any length greater than zero, this is not printed. if you modify your code, i.e., remove your 'if' condition, you will get an output of 0. try giving any command-line arguments, and the code will print the number of arguments given.

all the best,
Anandh
