Java - trying to apply what i've learned and class error

i am trying to apply what i have learned in JAVA and keep getting error line 2 which is the “public class payroll” … using the MU editor and it keeps erroring? what am i doing wrong>. saved in file so it should run. i’ve also tried Payroll.class and it also fails. confused here. is my syntax wrong?

public class Payroll
public static void main(String args)
double hourly = 0;
double weekly = 0;
double anually = 0;
double monthly = 0;

double hourly = 11.53;
double weekly = hourly * 40;
double annually = weekly * 52;
double monthly = annually/12;



I believe the file extension should be .java, not .py (that’s Python), and not .class.
