how to make 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: 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;
}
}
}
