1)Consider the below java code: import java

1)Consider the below java code:

import java.util.Scanner;

import java.io.File;

public class ScannerFromFile {

  public static void main(String[] args) {

     Scanner in = new Scanner(new File("test.in"));

     // do something ...

  }

}

              Write an exception to handle if the file “test.in” does not exist

2.Consider the below java code

public class Sample {

  public static void main(String[] args) {

     int num = Integer.parseInt(args[0]);

        ………………………………………………………..

     // The execution terminates if the value of num

     // is greater than 100

      System.out.println("The assertion passed...");

  }

}

Write an assertion that would terminate the program if the entered number is greater than 100
