My project freezes whenever i use a decimal number(using a DOUBLE) but works fine with whole numbers. Feel free to try the code out using the zip file or copying and pasting the code below. If you can fix this, just send me the edited code back my way. this is just a personal little project of mine

import java.util.Scanner;

/**

*/

/**

*/
public class EuclidsAlgorithm {
public static void main(String[] args) {
Scanner scan = new Scanner (System.in);
System.out.println("Type in the unit you are using(all lowercase, ex. m for metres):");
String mUnit = scan.nextLine();
System.out.println("Type in the rectangle length:");
double L = scan.nextDouble();
System.out.println("Type in the rectangle width:");
double W = scan.nextDouble();
if (L<W) {System.out.println("...so width is greater than length now?..");}
//double holder;
//holder = L;
while(L != W) {
if (L > W) {
L -= W;
} else if (L < W) {
W -= L;
}
//if ((L/10 < holder) && mUnit == "cm") {mUnit = "mm";}
//else if ((L/100 < holder) && mUnit == "m") {mUnit = "cm";}
//else if ((L/1000 < holder) && mUnit == "km") {mUnit = "m";}
}

if (L == W) {
System.out.println("The largest sqare can be "+ L + mUnit +" and "+ W + mUnit +".");
}

}
}

This is a forum dedicated to Eclipse and projects developed at eclipse.org, not for general programming questions. Followup generally also belongs in the forum itself. You might try Stack Overflow instead, but this looks a lot like a homework problem, so they're going to want a clearer explanation of exactly when it freezes and what you've already tried to solve this problem yourself.
