In Groovy, the next and continue keywords are used for skipping the current iteration in a loop.
The next keyword is used when you want to skip the current iteration and move to the next one in a loop.
Example:
for (int i = 1; i <= 10; i++) {
if (i == 5) {
next
}
println(i)
}
Output:
1
2
3
4
6
7
8
9
10
In this example, when the value of i becomes 5, the next keyword is used to skip the current iteration and move to the next one. So, the value 5 is not printed in the output.
The continue keyword is similar to the next keyword. It is also used to skip the current iteration and move to the next one. However, the difference is that the continue keyword proceeds to the next iteration of the loop without executing the rest of the statements in the current iteration.
Example:
for (int i = 1; i <= 10; i++) {
if (i == 5) {
continue
}
println(i)
}
Output:
1
2
3
4
6
7
8
9
10
In this example, when the value of i becomes 5, the continue keyword is used to skip the current iteration and move to the next one without executing the rest of the statements in the current iteration. So, the value 5 is not printed in the output.
