In Java, let's say I have...
let hello = 10;
Is it possible to retrieve hello's value (10) using the string reference 'hello'? Something like valueOf(....'hello'....) = 10
1 Answer
This is how you can retrive in Java. Also let is used in JavaScript not in Java.
public class Test {
public static void main(String[] args) {
String hello = "10";
int helloNum = Integer.valueOf(hello); //converting String "10" into int 10
int num = 10;
String numString = String.valueOf(num);//converting int 10 to string "10"
}
}

From my understanding this answer does not match the question. It's about dynamically accessing some variable by a given string, not about parsing the string.

@berse2212 is spot on

I've just found the answer, by using eval('hello') to get to the hello variable.

eval does not exist in Java. Was your question about javascript all along?
let(which does not conform to the Java naming conventions) that can be assigned an integer. Is your question about javascript?
