Java and JavaScript are indeed two different programming languages, so you can't directly convert one to the other. However, many concepts and syntax in Java are similar to those in JavaScript, so you can often translate Java code into JavaScript with some effort.
To convert the code you've provided to JavaScript, you'll need to make the following changes:
Remove the import statement at the top of the file, as JavaScript does not have a concept of importing other code files.
Change the public class declaration to a JavaScript function declaration. For example, public class EvaluateDivisors can be changed to:
function EvaluateDivisors() {
}
Replace the main method with a JavaScript function that will be called when the code is run. For example, public static void main(String[] args) can be changed to:
function run(args) {
}
Replace Java data types (e.g. int, long) with equivalent JavaScript data types (e.g. Number, String). For example, int result = 0; can be changed to let result = 0;.
Replace Java method calls (e.g. Long.parseLong) with equivalent JavaScript method calls (e.g. parseInt). For example, long a = Long.parseLong(args[0]); can be changed to let a = parseInt(args[0]);.
Convert any remaining Java syntax to JavaScript syntax. For example, for (int i = 0; i < 10; i++) can be changed to for (let i = 0; i < 10; i++).
Here is an example of what your code might look like after these changes:
function EvaluateDivisors() {
function run(args) {
try {
let a = parseInt(args[0]);
let b = parseInt(args[1]);
let k = parseInt(args[2]);
if (a <= 1 || b <= a) {
error("Error: must have 1 < A < B");
}
if (k <= 0 || k % 2 == 0) {
error("Error: K must be a positive odd number");
}
console.log(solution(a, b, k));
} catch (e) {
if (e instanceof IndexOutOfBoundsException) {
error("Usage: EvaluateDivisors A B K");
} else if (e instanceof NumberFormatException) {
error("Error: arguments must be integers");
}
}
}
function solution(a, b, k) {
if (prime(k)) {
return primeSolution(a, b, k);
}
let result = 0;
for (let n = Math.sqrt(a); n*n <= b; n++) {
let divisors = 3;
for (let m = 2; m < n && divisors <= k; m++) {
if (n*n % m == 0) {
divisors += 2;
}
}
if (divisors == k) {
result++;
<pre> }
return result;
}
function primeSolution(a, b, k) {
let result = 0;
let n = 2;
while (Math.pow(n, k - 1) < a) {
n++;
}
while (Math.pow(n, k - 1) <= b) {
if (prime(n++)) {
result++;
}
}
return result;
}
function prime(n) {
for (let m = 2; m <= Math.sqrt(n); m++) {
if (n % m == 0) {
return false;
}
}
return true;
}
function error(message) {
console.error(message);
process.exit(1);
}
}
Note that this code is not guaranteed to be correct, as it is only an example of what the converted code might look like. It is always a good idea to test and debug your code to ensure that it is working as expected.
