HELP programming noobs here.

We get a message saying

No user-supplied robotMain( )

and

we get “task 0xe62240 (tl) deleted: errno=1835009 (0xlc0001) status=1 (0x1)”

We decided to switch programming languages to JAVA and don’t know whats going on.

We are also not getting the top half of our driver station window to appear.

any and all help will be appreciated

Much Thanks.
Team 581

This is our code

package edu.wpi.first.wpilibj.templates;

import edu.wpi.first.wpilibj.SimpleRobot;
import edu.wpi.first.wpilibj.RobotDrive;
import edu.wpi.first.wpilibj.Timer;
import edu.wpi.first.wpilibj.Joystick;

public class Team581Robot
extends SimpleRobot {

RobotDrive drive = new RobotDrive(1,2);
Joystick leftstick = new Joystick(1);
Joystick rightstick = new Joystick(2);
Joystick kickerstick = new Joystick (3);



public void autonomous(){
    for (int i = 0; i <4; i++){
        drive.drive(0.5, 0.0);  //drive 50% fwd 0% turn
        Timer.delay(2.0);       //wait 2 seconds
        drive.drive(0.0, 0.25);
        drive.drive(0.5, .0); //drive 50% fwd 0% turn
        Timer.delay(1.0); //wait 1 seconds
        drive.drive(0.0, 0.75);  //drive 0% fwd 75% turn
        drive.drive(0.0, 0.25); //drive 0% fwd 25% turn
        drive.drive(0.5, 0.0); //drive 50% fwd 0% turn
        Timer.delay(1.0); //wait 1 second
        drive.drive(0.0, 0.75);
       
    }
    drive.drive(0.0, 0.0);      //drive 0% fwd, 0% turn
}

public void operatorControl() {
    while (true && isOperatorControl() && isEnabled())  //loop until change
    {
        drive.tankDrive(leftstick, rightstick);  //drive with joysticks
        Timer.delay(0.005);
    }
    
}

}

You said you switched to Java-

Did you update the cRIO for Java?

yes we switched to java when imaging the Crio.

The noRobotMain thing is normal, enable the robot to make it drive. as for the other error, try reformatting your cRio

we got it working our mentor actually showed up and help now we just need to get teleoperated working and we will be ready.
