Oh! I have a trick for arrays too.

lets assume we have an array named arr
then 
for(i:arr)
{
System.out.println(i);//Here i have just printed the elements but you can do anything
}
//Here each time when the loop runs the i contains the next element of the array cell

which means if arr[] would be{1,7,10,99,-10}
i will have the value 1 in first execution of the for loop
then i will have value 7 in next loop and so on....
comment if you liked?

         { 
              p=m+n;
              if(p%3==0)
              q=q+p;
              else
              q=p+4;
           }

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

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
