Help getting my code to run.

public class BusinessClass { // Length public static double inTOcm(double inches) { return 2.54 * inches; }public static double inTOmeter(double inches) { return 0.0254 * inches; }public static double inTOft(double inches) { return 0.083333 * inches; }public static double inTOyd(double inches) { return 0.0277778 * inches; }public static double inTOkm(double inches) { return 0.000254 * inches; }public static double ftTOmeter(double feet) { return 0.3048 * feet; }public static double ftTOyd(double feet) { return 0.0003048 * feet; }public static double ftTOkm(double feet) { return 0.33333 * feet; }public static double ftTOmiles(double feet) { return 0.000189394 * feet; }public static double ydTOmeter(double yard) { return 0.914 * yard; }public static double ydTOft(double yard) { return 3.0 * yard; }public static double ydTOkm(double yard) { return 0.00091444 * yard; }public static double ydTOmile(double yard) { return 0.000568182 * yard;

}

}
