Step by step
Solved in 2 steps
- What happened after the following Java code is run? - Compiler error - Exception - This final exam is very easy will be displayed - This final exam is easy will be displayedWrite a Java program to read the mobile number of an Employee. If the mobile number does not start with 9 or doesn't contain exactly 8 digits, throw a user defined exception InvalidNumberException. If the number entered is valid, display the message “correct mobile number is entered!” otherwise display “Entered mobile number is invalid!!” [Hint: Use String.valueOf(num).length() methods to first convert the gsm number (num) to string and then find the length of the string]This is a debugging question - The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. You also will use a file named DebugEmployeeIDException.java with the DebugTwelve4.java file. Code I was given- public class DebugEmployeeIDException extends Exception { public DebugEmployeeIDException() { super(s); } } // An employee ID can't be more than 999 // Keep executing until user enters four valid employee IDs // This program throws a FixDebugEmployeeIDException import java.util.*; public class DebugTwelve4 { public static void main(String[] args) { Scanner input = new Scanner(System.in); String inStr, outString = ""; final int MAX = 999; int[] emps = new int[4]; for(x = 0; x < emps.length; ++x) { System.out.println("Enter employee ID number"); inStr =…
- Please help me complete the following code using JAVA. (See image for the Objective) And please use this code as the foundation of your code (edit/modify it): import java.io.*; public class Q1320{ public static void main(String[] args) throws Exception { try { String d1 = args[0].trim(); String[] data = d1.split(" "); Q1320 obj = new Q1320(); String output = obj.q1320(data[0], data[1]); System.out.println(output); } catch (Exception e) { e.printStackTrace(); } } //Your code goes here public String q1320(String input, String n){ return "Replace this with the output of your algorithm"; } }Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Which of these keywords is used by the calling method to guard against the exception that is thrown by called method? A. tryB. throwC. throwsD. catchE. finally Part 2 - Which of the following is correct? A. All classes of Exception extend from Error.B. All classes of Error extend from Exception.C. All classes of Exception extend from Throwable.D. All classes of Throwable extend from Exception.E. All classes of Throwable extend from RuntimeException.Answer the following questions based on your knowledge of exception handling: Why should you use exception handler in a java program? “Introducing exception handler in a program is not always good” – Explain this statement with an example. Rewrite the following inefficient java code snippet to handle the runtime exception without using the try-catch.
- Create a TestTriangle class in an individual .java file. In the main method,(1) Create a Triangle object with default base and height values.(2) Create a Triangle object with specified base = 3 and height =4.Please solve this question, JAVA language for a programming fundamentals course. This is the question in text: Write java code to implement exception handling on your own example. Use the keywords throw new, throws, try, catch, and finally in the same program. Use a static method to implement the keyword throws.Please assist with non graded problem. Create a Calculator class that implements sum, subtraction, multiplication, and division operations, and throws an appropriate exception whenever the user attempts to perform a division by zero. Then develop a graphical interface (with JavaFx) for your calculator using TextField, Button, and Label objects, or any other graphical objects you like. Graphically display division by zero errors.
- Java : Write the code segments in main( ) and in methodA( ) for the following scenario: main( ) passes methodA an int variable called a. methodA generates an exception, but does not deal with it, if a is not between 1 and 100. Hint: main will try and catch the exception and methodA throws exception.Java Programming: Below is the lexer, shank and token files along with the shank.txt file. The shank file is the main method file. The lexer must break up the input text stream into lexemes and return a token object for each one in the shank.txt file. Make sure to fix the errors in the lexer.java file and show the complete code for lexer.java.There must be no error in the code at all. Run the whole code and show the output which the shank.txt must be printed out in the terminal. Attached is the rubric. Lexer.java package mypack; import java.util.HashMap;import java.util.List;import mypack.Token.TokenType; public class Lexer { private static final int INTEGER_STATE = 1;private static final int DECIMAL_STATE = 2;private static final int IDENTIFIER_STATE = 3;private static final int SYMBOL_STATE = 4;private static final int ERROR_STATE = 5;private static final int STRING_STATE = 6;private static final int CHAR_STATE = 7;private static final int COMMENT_STATE = 8; private static final…There are three clauses in Java’s Exception Handling. What are they? What are they for? Is it possible to create your own exception? Why would you think you might need it?
