Predict the output and the number of times the loop runs:

class Test {
    public static void main(String args[]) {
        int i;
        for(i=0;i<5;i++)
            System.out.println(i-i*i);
    }
}

State the difference between = and ==.

Give the output of the snippet:

int a=10,b=12;
if(a>=10)
a++;
else
++b;
System.out.println(a + "and" +b);
