Memory limit exceeded error on Sololearn.

Question

On Sololearn, I noticed that some of my codes could work on an IDE, but, when I run it on Sololearn, I get a "Memory limit exceeded" error, and my code doesn't compile.

Such as this code here:

import javax.script.ScriptException;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import java.util.Scanner;

/*Only works in an IDE - Memory Limit is exceeded if used in Sololearn.*/

public class Calc {
public static void main(String[] args) throws ScriptException {
Scanner scan = new Scanner(System.in);
while(scan.hasNext()){
ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine engine = mgr.getEngineByName("JavaScript");
try{
String equa = scan.next();
if(equa.equalsIgnoreCase("end")){
System.out.println("End.");
break;
}
System.out.println(engine.eval(equa));
}catch (Exception e){
System.out.println("ERROR! Bad input.");
}
}
}
}

Why does this happen?

Answer 1

I'd be very surprised to learn SoloLearn supported javax.script.*. They seem to only support a small subset of libraries.
