Question

What does regular colon ":" Means in java used in for loop for exmp

class jags {
public static void main(String[] args) {
int bucky[]= {3,4,5,6,7};
int total=0;

for(int x: bucky) {
total+=x;

}

System.out.println(total);
}
}
what the ":" does.

Answer 1

This is a for each style loop. It will iterate through each element of the array bucky assigning its value to the variable x within the for each loop.

: in this case acts as an "in" operator

Answer 2
