Can anyone help me in solving this java questions?

1)What is the value of x after evaluating:


x+ =x+++--x+4;


if x=3,before the evaluation?





2)Evaluate the following Java expressions where a,b,c are integers and d,f are floating point numbers.


The value of a=5,b=3 and d=1.5 .


(a)f =a+b/a


(b)c=d*a+b


(c)c+(a++)*d+a


(d)f=(++b)*b-a


(e)c=a-(b++)*(__d)





3)Illustrate '?' operator.





4)What is the difference between post-increment and pre-increment?If a=4 gives values of ++a and a++.





5)What is the meaning of variable++?





6)What does the following program output to the monitor:


int value=0;


int value=1;


value=count++;


System.out.println("value"+value"+coun...

Why not type those up into short Java programs and just try them out?





public class prob1


{


public static void main(String[] args) {


int x = 3;


x += x+++-x+4;


System.out.println("x is " + x);


}
