for each loop java list code example
Example 1: java foreach
List<String> someList = new ArrayList<String>();
// add "monkey", "donkey", "skeleton key" to someList
for (String item : someList) {
System.out.println(item);
}
Example 2: java loop through list
for (E element : list) {
. . .
}
Example 3: java iterate over list
for (int i = 0; i < crunchifyList.size(); i++) {
System.out.println(crunchifyList.get(i));
}
Example 4: iterate through an arraylist java
// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)
for (int i = 0; i < myArrayList.size(); i++) {
System.out.println(myArrayList.get(i));
// will print each index as it loops
}
Example 5: traversal of list in java
import java.util.ArrayList;
import java.util.Iterator;
public class IteratorSample {
public static void main(String[] args) {
ArrayList<String> list = new ArrayList<String>();
list.add("JavaFx");
list.add("Java");
list.add("WebGL");
list.add("OpenCV");
Iterator iterator = list.iterator();
while(iterator.hasNext()) {
System.out.println(iterator.next());
}
}
}
