http://www.guideforschool.com/1465944-isc-computer-practical-viva-questions/ I used this link to study for Viva last year, should be helpful in covering theory topics. :)

Name 2 exception classes and 2 error classes.

why is float x= 2.0/3;   not working?

+ 1 more questions by yoboyyy  

give the value of x; 1) int x= Math.max(1.9,2.5); //error? 2) int x=Math.round(1.5); 3) double x=10.0/3.0; 4)double x= 7/3; //2.0? 5) double x=Math.sqrt(-35); //which type of error please guys try all these and bluej and send output... i dont have bluej..
