creating an array of objects 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: array of objects javascript

var widgetTemplats = [
    {
        name: 'compass',
        LocX: 35,
        LocY: 312
    },
    {
        name: 'another',
        LocX: 52,
        LocY: 32
    }
]

Example 3: create array of objects javascript

let products = [
  {
    name: "chair",
    inventory: 5,
    unit_price: 45.99
  },
  {
    name: "table",
    inventory: 10,
    unit_price: 123.75
  },
  {
    name: "sofa",
    inventory: 2,
    unit_price: 399.50
  }
];
function listProducts(prods) {
  let product_names = [];
  for (let i=0; i<prods.length; i+=1) {
   product_names.push(prods[i].name);
  }
  return product_names;
}
console.log(listProducts(products));
function totalValue(prods) {
  let inventory_value = 0;
  for (let i=0; i<prods.length; i+=1) {
    inventory_value += prods[i].inventory * prods[i].unit_price;
  }
  return inventory_value;
}
console.log(totalValue(products));

Example 4: 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 5: java initialize object array

import java.util.stream.Stream;

class Example {
  
  public static void main(String[] args) {
    int len = 5;  // For example.
    
    // Use Stream to initialize array.
    Foo[] arr = Stream.generate(() -> new Foo(1))  // Lambda can be anything that returns Foo. 
                      .limit(len)
                      .toArray(Foo[]::new);
  }
  
  // For example.
  class Foo {
    public int bar;

    public Foo(int bar) {
      this.bar = bar;
    }
  }
}

Example 6: 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);
