455 Pointscompiling issues
just started courses in java but when i tried to compile my first program an error occurred: Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
i searched my computer for a _JAVA_OPTIONS file but it does not exist.
What is the problem and how do i fix it?

57,712 PointsOK - to compile you want to use the Java compiler. That is called javac with a c. If you compile and run like this, it'll work:
javac Introductions.java && java Introductions
Make sure you are using the same capitalisation. I put Introductions but you might need to use introductions`.
I hope that helps,
Steve.
P.S. Sorry for the slow reply; I was out - back home now!

57,712 PointsHi there,
That's not an error - just ignore it. Your program will run with that message at the beginning.
Did you get no output from your code?

455 Pointsi ignored the message and tried to run it anyway but i did not get an output from the code
Steve Hunter
57,712 PointsOK, can you post your code. Just paste it into here. And what did you type in your console to compile and run your code?
Steve.

455 Pointsimport java.io.Console;
public class Introductions {
public static void main(String[] args) {
Console console = System.console();
// Welcome to the Introductions program! Your code goes below here
console.printf("hello java");
}
}
i typed : java Introductions.java to compile and java Introductions to run
Steve Hunter
57,712 PointsYes. To compile, use the Java compiler. That's called javac not java, The answers above refer.
Let me know how you get on.
Steve.

1,602 PointsHi, I'm having the similar issue.
Code:
import java.io.Console;
public class Introductions {
public static void main(String[] args) {
Console console = System.console();
// Welcome to the Introductions program! Your code goes below here
console.printf("Hello, my name is something");
}
}
Console:
treehouse:~/workspace$ javac Introductions.java
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
treehouse:~/workspace$ java Introductions
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
Getting no output...
Steve Hunter Do you think you can help out with this?

1,602 PointsSolution is to (Top Left select File > Save) the file. Then proceed to run Java compiler and then the code again.
Steve Hunter
57,712 PointsOh yes. Make sure you save your changes before compiling!
It's past midnight here so time for sleep!
Goodnight all!
Steve Hunter
57,712 PointsYou haven't run your code; you have just compiled it. You compile with:
javac Introductions.java
You run with:
java Introductions
You can do both at once with:
javac Introductions.java && java Introductions
Good luck!
Steve.
