java difference StdOut vs System.out.println [closed]

Question

I have just started working on java, As i downloaded the eclipse and created a java project. Project was working fine, then i imported a class but it's not working due to following lines

StdOut.println(p + "  " + q);

after searching i have replaced it with

System.out.println(p + "  " + q);

and same way for input.

I tried importing system.io.* didn't worked. then i tried import StdIn not worked

As i can feel is that it may be due to different project template/type. and tutorials links will also be helpful. Thanks

Most likely, you are enrolled in a course which is attempting to simplify the course without delving into the complexities of the Java programming language. You can download the individual classes here: introcs.cs.princeton.edu/java/stdlib – Perry

Answer 1

StdOut is not a class that comes in the JDK.

Though, StdOut is commonly used in school projects.

I also had added the jar file for the said stdout class in my project, – Amphisbaena

@HaseebAsif: What IDE are you using? Eclipse? – Marilumarilyn

I am using eclipse juno for java developers i can see the added jar file under referenced libraries – Amphisbaena

@HaseebAsif: Try reading this link. – Marilumarilyn

Already accomplished this thing but yet no luck :-( – Amphisbaena

It did worked for me when i added the jar file specifically for this project. Before this i was trying to add for all project by going windows -- preferences -- java and adding class variables there – Amphisbaena

@HaseebAsif: If you want to include the jar for ALL projects, goto Window -> Preferences -> Java -> Installed JREs. Find your default JRE and click edit to add the JARs you want. – Marilumarilyn

@HaseebAsif: Actually you should probably do it this way. – Marilumarilyn
