Example 1 with IntIterable

use of org.eclipse.collections.api.IntIterable in project eclipse-collections by eclipse.

the class IntInterval method chunk.

@Override
public RichIterable<IntIterable> chunk(int size) {
    if (size <= 0) {
        throw new IllegalArgumentException("Size for groups must be positive but was: " + size);
    }
