Hello,
Maybe you could post some code (don't forget to use the code formatting by pressing the *code* button ;-)), so that we could have a clearer idea of what you are trying to do ?
Usually, to output something to the console (when running a code from command line), you must use the System.out.println() method.
Hope this help !
I m using System.out.print() for displaying in the common promt but nothing comes after the compliation.
I have to do an assignment on java but due t o this i m stuck please help me out
II write this program
public class welcome1
{
public static void main( String arg[] )
{
System.out.println("HI");
}
}
Save it as welcome1.java in C:\src\welcome1.java
when i open the command promt and write
javac c:\src\welcome1.java the cursor blink for a while and then
C:\> this comes on the screen
the compiler complies the program but the output (HI) does not come on the screen
Hello,
By using javac
command, you only COMPILE your program... You are not actually running it...
To run it, you have to run the follonwing, from command prompt:
java c:\src\welcome1
Hope this helps...
PS: you didn't use the code tag to post your code. Code lines are more easily readable when you post them using the code button

Java is case sensitive. If the class is named welcome1 then the command should be "java welcome1" and if the class is named Welcome1 then the command should be "java Welcome1" (Sorry if I confused that part, I did not look closely at your first post.)
The recommended way to let java know where to look is to use the -classpath option. If your .class file is in the current directory and the class name is Welcome1, then use java -classpath . Welcome1Notice the spaces and the dot(.) between -classpath and Welcome1.
