I'm trying to print multiple random numbers for a give time using lettertest(num) I also need to return the number to set a new value for a old numer. How?

public static int timewait(int times){     // print Rand number
		int num;
		for(int i=0; i<times; i=i+1){
			num = Rand(0);
		try {
			Thread.sleep(1000);
			} catch(InterruptedException e) {} 
			lettertest(num);
		}
		return num;

What programming language is that ?

anonymous · Answer

probably java, I haven't learnt about threads and catching exceptions yet, so not sure what try {...} does

anonymous · Answer

@Tomas
Basically, the code inside the try {} block is executed, but whenever an exception (in this case, the program is specifically expecting an InterruptedException) occurs within that block the catch {} block right after it will handle it, and therefore control will be transferred to the part inside the except {} block, instead of just having the entire program crash :-D

anonymous · Answer

oops I meant the catch {} block in the last part of my explanation (I get confused since except is the keyword used in Python's try-except clauses)

anonymous · Answer

anyway in this piece of  code the try-except clause is just used so that the whole program doesn't crash in case something weird happens when calling Thread.sleep

anonymous · Answer

so when exception comes it does nothing and just continues program?

anonymous · Answer

yeah, notice the empty braces after the except()

anonymous · Answer

oops I meant catch() :-P

anonymous · Answer

it will always return 1 number or it won't work at all because I don't know such method Rand and I don't have idea what lettertest does

IS IT JAVA ?

anonymous · Answer

It is definitely some kind of Java.
