Why TLE in Java? Same algorithm is getting accepted in Python

general
1

For this problem, my algorithm is giving TLE in Java but it’s getting accepted in Python.
What am I missing?

//imports for BufferedReader
import java.io.BufferedReader;
import java.io.InputStreamReader;

//import for Scanner and other utility classes
import java.util.*;

class TestClass {
    public static void main(String args[] ) throws Exception {
        //Scanner
        Scanner s = new Scanner(System.in);
      
        int t= s.nextInt();
        // System.out.println(t);
        while(t>0){
            
            int n = s.nextInt();
            double a[]=new double[n];
            
            double b[]=new double[n];
            for(int i=0;i<n;i++){
                a[i]=s.nextDouble();
                 if (i==0 || a[i]>=b[i-1]){
                    b[i]=a[i];
                }
                else{
                    double mult=Math.ceil(b[i-1]/a[i]);
                        b[i]=a[i]*mult;
                }
            }
             for(double arr:b){
                  System.out.print((int)arr+" ");
             }
         System.out.println();
            t--;
        }          
    }
}
