ICSE − Q & A

Catch on to fire if you must,sometimes everything needs to burn to the ground so that we may grow.

Could someone please provide me with an example of pure and impure functions that I could write if asked?

I recently realized that 'System.out.println()' is a great example of function overloading.

To get a random integer in the range [min, max), int randomInt(int min, int max) { return Math.floor(min + (Math.random() * (max - min))); } To get a random double in range [min, max): double randomDouble(int min, int max) { return min + (Math.random() * (max - min)); }

What's the use of static guys?

The bodyless loop whose function in the book is given that"It is used to create delay" is actually not taken as a delay for humans as the i9 7980x processor overclocked at 4.6GHz processes it so quickly that hardly i can see any delay
but if you actually want a delay u can use



Thread.sleep(1000);//here 1000 means 1 second delay 


time is given inside the brackets is in milli-seconds

but whenever u use it dont forget to wrap this function with try-catch block




try{
Thread.sleep(1000);
}
catch(InterruptedException e){
System.ot.println("Technical Problem");
}

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?

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;
