Question

 int a = 3;
int b = -2;
if((a>0)&&(b>0)){
    if (a>b) {
        System.out.println("A");
    } else {
        System.out.println("B");
    }
} else if ((b<0)||(a<0)) {
    System.out.println("C");
} else {
    System.out.println("D");
}

Answer 1

If the above program is executed in java then value of variable "a" is 3 and value of variable "b" is -2

By using braching statement(if .. else statement) a> 0 and b > 0 , here logical and operator is used if the bothe condition is true then it will execute if part otherwise it will execute else part .

In First nested if part it check a>b it print A

else it print B

In second else part (b<0) || (a<0) it print "C " and actually this condition is true , because here logical or operator is used , here if one condition is true it will execute i, e value of b = -2 and it true because it check b< 0 and value of a is 3 it check a<0 it is false , hence according to logical or if one codition is true operation will perform .

Otherwie in last else part it will print "D"

Code :

public class First

{

     public static void main(String []args)

     {

            int a = 3;

            int b = -2;

            if((a>0)&&(b>0))

            {

                if (a>b)

                {

                    System.out.println("A");

                } else

                {

                    System.out.println("B");

                }

            }   

            else if ((b<0)||(a<0))

            {

                System.out.println("C");

            }

            else

            {

                System.out.println("D");

            }

}

}

Output:

C
