You can filter a stream in Java using the Stream API's filter() method. The filter() method is to be used to filter the Elements in a Stream and can take a Predicate object to define the criteria for filtering. The filter() method creates a new Stream including only the Elements that match the given Predicate. Example: List<String> fruits = Arrays.asList("Apple", "Banana", "Mango", "Orange"); // Using filter to filter fruitnames starting with letter 'M' Stream<String> filteredFruits = fruits.stream().filter(fruit -> fruit.startsWith("M")); filteredFruits.forEach(System.out::println); // Output Mango

Foreach is a type of loop in Java that enables the user to iterate through elements or a collection of elements in an array or list.

There are a few ways to draw a square in Java. 1. Using a method from the Graphics class: public void drawSquare(Graphics g, int width, int height, int x, int y) { g.drawRect(x, y, width, height); } 2. Using the Rectangle class in the java.awt package: Rectangle square = new Rectangle(x, y, width, height); 3. Using Java2D (part of the Java2D API): Shape square = new Rectangle2D.Double(x, y, width, height);
