Why We Use ":" for Inside the for loop ?

Question

I Can't Understand

Answer 1

In which language? Your profile says you're learning Java; a colon is sometimes used to cycle through an array.

For example, if you have an integer array "arr" that is equal to [1, 2, 3] then you can use:

for (int i: arr) {
System.out.println(i);
}

This outputs:
1
2
3

This can also be used to cycle through a list of objects and call their methods.
