ICSE − Q & A

Guys all of you must have faced the problem of printing a particular array as it requires the user to type out another for loop which is time consuming tedious and boring
heres a trick but u ll have to import java's utilility package by import java.util.*
just say u wanna print array named arr
type :- System.out.println(Arrays.toString(arr));
the output is like this : [a,b,c,d] try this one out

If z=13,y=10,a=100.
Find a/=z++ + ++z*(- -y  -  y- -)%3 + z++ - ++y;

is Math.random(), shift and bitwise operators included in the syllabus?

Just thought I would share as a similar question came in our prelims :

 String s = "hi";
 System.out.println(s.indexOf("1"));

Output for this is -1
