Find the Error in Class Code

[Humphrey Bogart]

Hello. I copying some code for a class from a text on Java. Even though I beleive I have gotten the code correct, I get error messages, Can anyone helps me resolve this?

The code:

public class Primefinder implements Runnable {
	public long target;
	public long prime;
	public boolean finished = false;
	private Thread runner;

	PrimeFinder(long inTarget) {
		target = inTarget;
		if (runner == null) {
			runner = new Thread(this);
			runner.start();
		}
	}

	public void run() {
		long numPrime = 0;
		long candidates = 2;
		while (numPrime < target) {
			if (isPrime(candidate)) {
				numPrimes++;
				prime = candidate;
			}
			candidate++;
		}
		finished = true;
	}
	
	boolean isPrime(long checkNumber) {
		double root = Math.sqrt(checkNumber);
		for (int i =2; i <= root; i++) {
			if (checkNumber % i == 0)
				return false;
		}
		return true;
	}
}

The error messages on compiling:
"invalid method declaration; return type required"
"PrimeFinder(long inTarget) {'

Thank you.

Java is case sensitive - look at the class name and the constructor name.
The f is in a different case

Hi
you are declaring Primefinder class constructor PrimeFinder .F should be in small case i.e. exactly same as class name
