3. Show the output of the following program and briefly explain your answer. public class Test { public static void main(String[] args) { } String s = "Java"; StringBuilder builder = new StringBuilder(s); change(s, builder); System.out.println(s); System.out.println(builder); private static void change (String s, StringBuilder builder) { s = s + " and HTML"; builder.append(" and HTML"); } }

Java Below is how the expression is represented. This expression is also known as an ”in-fix” string expression 10 * 2 + 15 / 3   Here you have to remember that parentheses and/or operators have precedence, where some sub-expressions need to be calculated earlier than other sub-expressions. Further, there are space(s) between operands/operators in the expression. So your solution needs to think of these aspects.   You will solve the problem as stated below: (1) Design a simple calculator that helps you solve the expression given. For your assistance you can use the Stack class provided in java. Please be reminded that you need to design the calculator and not use in-built math methods from the programming language library to solve the expression.  Also at the end of the program as a comment mention the time and space complexity of your solution. Time and space complexity.   Very Very Important : (1) Your code should be well commented which explains all the steps you are performing to…

What are the different types of variables are there in Java? Name at least three and discuss their characteristics.

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…

Fill in the proper blank. JDB is used for finding and fixing ____ inside the Java program.

This assignment will help you to get started with NetBeans and using Java compiler:   To begin, put a block comment at the beginning of your Java file (and every Java source file in the future) with the assignment number, assignment title, program author [your name], and the date it's due. Next, similar to the programs presented in the first chapter of the textbook, use System.out object to display the following information: Your first name The name of the operating system you are using The name of your project (or simply the folder name if not using the IDE) The name of the class that contains the main() method in your source file. Note: Your program should print each of the above items on a separate output line. "The name of the class that contains the main() method in your source file.public class MyClass {    public static void main(String[]) {        System.out.println( "Hi" );    }}
