Exception in thread "main" java.lang.NoClassDefFoundError: Solution (wrong name: solution)

class solution
{
    void table(final int n) {
        for (int i = 1; i <= 10; i++) {
            System.out.println(n + " X " + i + " = " + n * i);
        }
    }
}

class Solution {
    public static void main(final String args[]) {
        solution os = new solution();
        Scanner ob = new Scanner(System.in);
        int n = ob.nextInt();
        os.table(n);
    }
}

After running java Solution
this is the error message

could not find the solution for it this error starts popping when I have upgraded to Java 14 earlier I have java 8 this code runs with no problem.

Always follow best practices. Don't use the same name for class in the same package.

package com.india.demo;

public class solution
{
    public void table(final int n) {
        for (int i = 1; i <= 10; i++) {
            System.out.println(n + " X " + i + " = " + n * i);
        }
    }
}
------------------
package com.india.string;

import java.util.Scanner;

import com.india.demo.solution;

public class Solution {
    public static void main(final String args[]) {
        solution os = new solution();
        Scanner ob = new Scanner(System.in);
        int n = ob.nextInt();
        os.table(n);
    }
}

This will work.
