Program Plan Intro
“IntStream” in Java:
- It is a stream of primitive “int” values.
- The “java.util.stream” package contains “IntStream” and the user can find many functions present in the normal “Stream <T>”.
- It will return a sequential “IntStream” containing a single element.

Might there be a way to directly access commonly used operators, such as the arithmetic operators or the stream operators, with enumeration types? For example, would overloading these operators be a good solution? Why or why not?
Is it possible to quickly access frequently used operators while dealing with enumeration types,
such as the arithmetic operators and the stream operators? Is it possible to get a satisfying
outcome by, say, overloading these operators? What are the benefits and drawbacks of this
approach?

Write an immutable data type Term.java that represents an autocomplete term-a query string and an associated integer weight. You must implement the following API, which supports comparing terms by three different orders: lexicographic order by query string (the natural order); in descending order by weight (an alternate order); and lexicographic order by query string but using only the first r characters (a family of alternate orderings). The last order may seem a bit odd, but you will use it in Part 3 to find all query strings that start with a given prefix (of length r). public class Term implements Comparable { // Initializes a term with the given query string and weight. public Term (String query, long weight) // Compares the two terms in descending order by weight. public static Comparator byReverseWeight0rder () // Compares the two terms in lexicographic order, // but using only the first r characters of each query. public static Comparator…arrow_forwardComplete the drawTriangle() function in script.js that draws a triangle with asterisks (*) based on the triangleSize parameter. Ex: drawTriangle(4) outputs to the console a triangle with triangleSize 4, so the longest side (4 asterisks) appears on the bottom line: * ** *** **** Hint: Use a loop inside a loop to complete drawTriangle(). The outer loop is responsible for outputting each asterisk line, and the inner loop is responsible for building the asterisk line with the appropriate length by concatenating asterisks to a single string.

- When working with enumeration types, such as the arithmetic operators and the stream operators, is it possible to rapidly access operators that are often used, such as the arithmetic operators and the stream operators?

What are the arguments for and against doing so?arrow_forwardin c++ Given the string "An elephant." Store it in a char pointer Print on one line the letter on the index 0.
