Overview
In this tutorial, we show you how to
print all elements of an
ArrayList in Java. In this example below, we will display all the elements of a
ArrayList using Loop.
Print All Elements of an ArrayList using for (Object object : list)
package com.jackrutorial;
import java.util.ArrayList;
import java.util.List;
public class PrintAllElementsOfAnArraylistExample1 {
public static void main(String[] args) {
List<String> pgLangs = new ArrayList<String>();
pgLangs.add("Java");
pgLangs.add("AngularJS");
pgLangs.add("ReactJS");
pgLangs.add("Spring MVC");
for (String lang : pgLangs) {
System.out.println(lang);
}
}
}
Output
Java
AngularJS
ReactJS
Spring MVC
Print All Elements of an ArrayList using Loop for iterating ArrayList
package com.jackrutorial;
import java.util.ArrayList;
import java.util.List;
public class PrintAllElementsOfAnArraylistExample2 {
public static void main(String[] args) {
List pgLangs = new ArrayList();
pgLangs.add("Java");
pgLangs.add("AngularJS");
pgLangs.add("ReactJS");
pgLangs.add("Spring MVC");
for (int i = 0; i < pgLangs.size(); i++) {
System.out.println(pgLangs.get(i));
}
}
}
Output
Java
AngularJS
ReactJS
Spring MVC
Print All Elements of an ArrayList using ArrayList.iterator()
package com.jackrutorial;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class PrintAllElementsOfAnArraylistExample3 {
public static void main(String[] args) {
List<String> pgLangs = new ArrayList<String>();
pgLangs.add("Java");
pgLangs.add("AngularJS");
pgLangs.add("ReactJS");
pgLangs.add("Spring MVC");
Iterator<String> iterator = pgLangs.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}
}
}
Output
Java
AngularJS
ReactJS
Spring MVC
Print All Elements of an ArrayList using java.util.ArrayList.forEach() in JDK 8
package com.jackrutorial;
import java.util.ArrayList;
import java.util.List;
public class PrintAllElementsOfAnArraylistExample4 {
public static void main(String[] args) {
List pgLangs = new ArrayList();
pgLangs.add("Java");
pgLangs.add("AngularJS");
pgLangs.add("ReactJS");
pgLangs.add("Spring MVC");
//lambda expression
pgLangs.forEach(s -> System.out.println(s));
//method reference
pgLangs.forEach(System.out::println);
}
}
Output
Java

Print All Elements of an ArrayList using while() loop
package com.jackrutorial;
import java.util.ArrayList;
import java.util.List;
public class PrintAllElementsOfAnArraylistExample5 {
public static void main(String[] args) {
List pgLangs = new ArrayList();
pgLangs.add("Java");
pgLangs.add("AngularJS");
pgLangs.add("ReactJS");
pgLangs.add("Spring MVC");
int i = 0;
while (pgLangs.size() > i) {
System.out.println(pgLangs.get(i));
i++;
}
}
}
Output
Java
