Java – List Iterate Example

[code lang=”java”]import java.util.Arrays;
import java.util.Iterator;
import java.util.List;

public class ArrayToList {

public static void main(String[] argv) {

String sArray[] = new String[] { "Array 1", "Array 2", "Array 3" };

// convert array to list
List<String> lList = Arrays.asList(sArray);

// iterator loop
System.out.println("#1 iterator");
Iterator<String> iterator = lList.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}

// for loop
System.out.println("#2 for");
for (int i = 0; i &lt; lList.size(); i++) {
System.out.println(lList.get(i));
}

// for loop advance
System.out.println("#3 for advance");
for (String temp : lList) {
System.out.println(temp);
}

// while loop
System.out.println("#4 while");
int j = 0;
while (j < lList.size()) {
System.out.println(lList.get(j));
j++;
}
}
