Find the error :

x = 3;	
y = 4;	
z = math.power(x*x, y/2);	

Predict the output :

class FindFac {
    public static void main (String args[]) { 
        for(int i = 2; i <= 100; i++) {
            System.out.print("Factors of" + i + ":  ");
            for(int j = 2; j < i; j++)
                if((i % j) == 0) 
                    System.out.print(j + " "); 
                System.out.println();
        }
    }
}

Find the error

for(count = 0,  count < 5,  count = count + 1)	
System.out.println("This is  count:" + count);	
    System.out.println("Done!");	

Predict the output :

class Power {
    public static void main(String args[]) { 
        int e = 5, result, i;
        result = 1 ; 
        i = e ; 
        while(e > 0) {
            result *= 2 ;
            e--;
        }
        int n = result /2, p = i - 1;
	    System.out.println("2 to the power of " + i + " is " + result);
        System.out.println("2 to the power of " + p + " is " + n);
    }
