arrays of objects in java code example

Example 1: java create array with values

//Given values must match array type
int[] myIntArray = {1, 2, 3};

Example 2: array objects java

obj array[] = new obj[10];

for (int i = 0; i < array.length; i++) {
  array[i] = new obj(i);
}

Example 3: creating array of objects in java

class Main{
   public static void main(String args[]){
     //create array of employee object  
    Employee[] obj = new Employee[2] ;
 
     //create & initialize actual employee objects using constructor
     obj[0] = new Employee(100,"ABC");
     obj[1] = new Employee(200,"XYZ");
 
     //display the employee object data
     System.out.println("Employee Object 1:");
     obj[0].showData();
     System.out.println("Employee Object 2:");
     obj[1].showData();
  }
}
//Employee class with empId and name as attributes
class Employee{
  int empId;
  String name;
  //Employee class constructor
  Employee(inteid, String n){
     empId = eid;
     name = n;
  }
public void showData(){
   System.out.print("EmpId = "+empId + "  " + " Employee Name = "+name);
   System.out.println();
 }
}

Example 4: java array object

class ObjectArray{
   public static void main(String args[]){
     Account obj[] = new Account[2] ;
     //obj[0] = new Account();
     //obj[1] = new Account();
    obj[0].setData(1,2);
    obj[1].setData(3,4);
    System.out.println("For Array Element 0");
    obj[0].showData();
    System.out.println("For Array Element 1");
     obj[1].showData();
  }
}
class Account{
  int a;
  int b;
 public void setData(int c,int d){
   a=c;
   b=d;
 }
 public void showData(){
   System.out.println("Value of a ="+a);
   System.out.println("Value of b ="+b);
 }
}
