What the heck??? Need urgent help!

[Julian]

Okay so whenever I try to compile something, it works normal, and if theres no problems, it will say something about System.out.printIn(); method...heres my example i forgot the ";" after something and it said one error, then once i fixed it it came with a bunch of crap...Im using 1.6 on Linux...heres my command line trying to compile it:


julian@ubuntu:~/Desktop/Java$ javac SetPoints.java
SetPoints.java:13: ';' expected
location.y=6
^
1 error






Then i fixed it by putting the ";" after "location.y=6"







julian@ubuntu:~/Desktop/Java$ javac SetPoints.java

Heres my script:
import java.awt.Point;

class SetPoints {

public static void main(String arguments[]) {

System.out.printIn("Starting location:");
System.out.printIn("X equals " + location.x);
System.out.printIn("Y equals " + location.y);

System.out.printIn("\nMoving to (7,6)");
location.x=7;
location.y=6;

System.out.printIn("\nEnding location:");
System.out.printIn("X equals " + location.x);
System.out.printIn("Y equals " + location.y);
}
}

It's telling you (many times) that it can't find the location variable, that you've never declared it, and it's right. Solution: declare and initialize the variable.

Also, please avoid using "urgent" in your posts as it has the opposite effect that you've intended -- usually less folks will want to help you because it's not really our urgency, and no one wants to feel pushed, least of all volunteers who help for free.

Luck.

yeah sorry im new to this site (first time today) and im pretty new to java...how would you declare and initialize the variable (sorry for so many questions)

Also,

System.out.printIn =/= System.out.println

yeah sorry im new to this site (first time today) and im pretty new to java...how would you declare and initialize the variable (sorry for so many questions)

You give the variable's type, it's name and then a value. For instance here are three variable declarations with initialized values:

int myVar = 3;
Point aPointVar = new Point(0, 0);
Dimension mySize = new Dimension(400, 200);
//... etc ...
