How do I comment this Java code? I'm new.?

I'm new to Java and honestly what I see when I look at this are methods. I'm not even 100% what to write...I've commented what I think I know to be right, the methods at the top. How would I comment the lines toward the bottom? What am I doing in Java class again? C# is my buddy.

int value;

//constructor

MyInteger(int newValue) { value = newValue; }

// get method that returns value

public int getValue() { return value; }

//returns true if even

public static boolean isEven(int num) { return (num%2 == 0); }

//returns true if odd

public static boolean isOdd(int num) { return !isEven(num); }

//returns true if a prime

public static boolean isPrime(int num) {

for (int f=2; f<num/2; f++) if (num%f==0) return false;

return true;

}

public static boolean isEven(MyInteger n) { return n.isEven(); }

public static boolean isOdd(MyInteger n) { return n.isOdd(); }

public static boolean isPrime(MyInteger n) { return n.isPrime(); }

public boolean isEven() { return isEven(value); }

public boolean isOdd() { return isOdd(value); }

public boolean isPrime() { return isPrime(value); }

public boolean equals(int n) { return (value == n); }

public boolean equals(MyInteger n) { return equals(n.getValue()); }

public static int parseInt(String s) { return Integer.parseInt(s); }

public static int parseInt(char[] s) { return parseInt(new String(s)); }

}
