In this tutorial, we will learn about foreach in java8 using streams
In java8, We can easily iterate a list using streams.
Streams API provided a lot of features. In this post, we are going to see about foreach
Syntax
stream().forEach({operations});Example
import java.util.ArrayList;
import java.util.List;
public class ForEachExample {
public static void main(String[] args) {
try {
List studentList = new ArrayList();
Student student = null;
student = new Student();
student.setId(1);
student.setName("Rajesh");
student.setAddress("Mumbai");
studentList.add(student);
student = new Student();
student.setId(1);
student.setName("Kumar");
student.setAddress("Chennai");
studentList.add(student);
studentList.stream()
.forEach(x -> System.out.println("Name is " + x.getName() + " Address is " + x.getAddress()));
} catch (Exception e) {
e.printStackTrace();
}
}
}
Student.java
public class Student {
private int id;
private String name;
private String address;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
Output
Name is Rajesh Address is Mumbai
Name is Kumar Address is ChennaiRelated Article
