array of object in java code example

Example 1: array objects java

obj array[] = new obj[10];

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

Example 2: java array object

Class obj[]= new Class[array_length]

Example 3: how to make array of objects in java and use it

//create class
class enemies {
   int marks;
}
//create object array
enemies[] enemiesArray = new enemies[7];
//assign value to object
enemiesArray[5] = new enemies(95);

Example 4: java class array of objects

public class MainClass
{  
    public static void main(String args[])
    {
        System.out.println("Hello, World!");
        //step1 : first create array of 10 elements that holds object addresses.
        Emp[] employees = new Emp[10];
        //step2 : now create objects in a loop.
        for(int i=0; i<employees.length; i++){
            employees[i] = new Emp(i+1);//this will call constructor.
        }
    }
}

class Emp{
    int eno;
    public Emp(int no){
        eno = no;
        System.out.println("emp constructor called..eno is.."+eno);
    }
}

Example 5: array object java

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);
 }
}
