Where and why we use ":" this one?pls tell me..

Question

java

Answer 1

Ah okay... That notation is called an "enhanced for loop". It requires less writing and less lines than the regular loop and it is used to traverse and get elements of an array...

Basically you have:
for (variableName : array)
//do something with the variable

So it takes each element of the array and puts it in the variable

Look at the code below. The two loops do the same thing but the enhanced loop makes things simpler

Could you be a little more specific? The clearer your question, the better we can help

Answer 3

public class Program {
public static void main(String[] args) {
int[ ] primes = {2, 3, 5, 7};

for (int t: primes) { /*just like here , why they use ":"? */
System.out.println(t);
