	if (n > 1) {
		for (int x = 1; x < n ; x++) {
			if (n % x == 0 && x != 1) {
				return false;
			}
		}
	} else {
		return false;
	}
	return true;
}

#4 Exponents

	double result = 1;

	for (int n = 0; n < exponent; n++) {
		result = base * result;
	}

	return result;
}

/***or recursive****/

public double pow2(double base, int exponent) {

	if(exponent == 1){
		return base;
       }else{
		return pow2(base, exponent-1) * base;
	}

}

#10 ToUpperCase

public String toUpperCase(String str) {
	StringBuffer strBuff = new StringBuffer();

	for (int x = 0; x < str.length(); x++) {
		int cInt = str.charAt(x);

		if (cInt >= 97) {
			char temp = (char) (cInt - 32);
			strBuff.append(temp);
		} else {
			strBuff.append(str.charAt(x));
		}
	}

	return strBuff.toString();
