    Question hi, beginner. need help with code

    hi i am a total beginner at java code.
    i am trying to write a program for this problem.

    Land Calculation

    One acre of land is equivalent to 43,560 square feet. Write a program
    that calculates the number of square feet in a tract of land with 3.5
    acres. Hint: Multiply the size of the tract of land (in acres) by the
    number of square feet in an acre to get the number of square feet in
    the tract.

    a) You must have a variable called nrAcres where you will store the
    number of acres in the track.

    b) Output must look as follows:

    Size of land in acres: 3.5
    Size of land in square feet: 152460

    c) if the value of the variable nrAcres is changed the output should
    change accordingly. In other words: it would be wrong to have the
    following statement:

    System.out.println("Size of land in square feet: 152460");

    previous statement will print the correct output but will not change
    if you change the value of nrAcres.

    this is what i got so far

    public class Land
    {
    public static void main(String[] args){
    double nrAcres = 3.5;
    int feetInAcre = 43560;
    double feetInTract = nrAcres * feetInAcre;
    System.out.println("Size of land in acres: " + nrAcres + "\nSize of land in square feet: " + feetInTract);
    }
    }

    i tried to compile it but it says

    error: class names, Land, are only accepted if annotation is explicitly requested 1 error

    what is wrong with my code

    Hi,

    I think you missed ".java" at the time compilation. Try to complile like this "javac Land.java" and run the program "java Land"
