How to draw a rectangle in Java?
You can draw a rectangle in Java using the drawRect() method. This method is part of the Graphics class, which you access through a Graphics2D object. Here is an example:
Graphics2D g2d = (Graphics2D) g;
g2d.drawRect(x, y, width, height);
Where x and y are the coordinates of the upper left corner of the rectangle, width is the width of the rectangle and height is the height of the rectangle.

How do I make an API call in JavaScript?
Making an API call in JavaScript can be done using a couple different methods. One method is using AJAX (Asynchronous JavaScript and XML). This approach involves the use of Javascripts XMLHttpRequest object and callback functions.
An example of making an API call with AJAX in Javascript is below:
//Create a new XMLHttpRequest object
let xhr = new XMLHttpRequest();
//Specify the type of request, URL, and whether the request should be async or not
xhr.open('GET', 'http://myapi.example.com/data', true);
//Send the request
xhr.send();
//Handle the response
xhr.onreadystatechange = function() {
if(xhr.readyState == 4 && xhr.status == 200) {
//Parse the response
let response = JSON.parse(xhr.responseText);
//Do something with the response
console.log(response);
}
}
Another method to make an API call in Javascript is using the fetch() API, which is built into modern browsers. This method involves using the fetch() function and promises to handle asynchronous code.
An example of making an API call with the fetch() API in Javascript is below:
//Make the request
fetch('http://myapi.example.com/data')
.then(function(response) {
//Parse the response
return response.json();
})
.then(function(response) {
//Do something with the response
console.log(response);
});
