initializing object inside array code example
Example 1: creating array of objects in java
class Main{
public static void main(String args[]){
Employee[] obj = new Employee[2] ;
obj[0] = new Employee(100,"ABC");
obj[1] = new Employee(200,"XYZ");
System.out.println("Employee Object 1:");
obj[0].showData();
System.out.println("Employee Object 2:");
obj[1].showData();
}
}
class Employee{
int empId;
String name;
Employee(inteid, String n){
empId = eid;
name = n;
}
public void showData(){
System.out.print("EmpId = "+empId + " " + " Employee Name = "+name);
System.out.println();
}
}
Example 2: java initialize object array
import java.util.stream.Stream;
class Example {
public static void main(String[] args) {
int len = 5;
Foo[] arr = Stream.generate(() -> new Foo(1))
.limit(len)
.toArray(Foo[]::new);
}
class Foo {
public int bar;
public Foo(int bar) {
this.bar = bar;
}
}
}
