construct 2 methods: Void input() and void maxNum(). The input method should allow user to input 3 integers while maxNum method should be able to generate the highest number. Display the highest number in your program.
Write a program that displays the income tax due on taxable income entered by the user. Have the user enter the tax in the main() method, and then call a calcTax() method to compute the tax. Print the value returned.
The calcTax() method should have one parameter - income - and return a double - tax.
The tax is calculated as follows:
Income
Tax Due
$0 - $50,000
5%
$50,000-$100,000
$2,500 + 10% of (income > $50,000)
> $100,000
$7,500 + 15% of (income > $100,000)
6. Write a method that reads three strings from the keyboard. Although the strings are in no particular order, display the string that would be second if they were arranged lexicographically.
7. Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a…

Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium. The health insurance method asks users whether they smoke; the premium is $550 for smokers and $345 for nonsmokers. The auto insurance method asks users to enter the number of traffic tickets they have received…arrow_forwardWrite a program that asks the user to enter a character. Then pass the character to the following methods. a) isVowel() – returns true if the character is a vowel b) isConsonant() – returns true if the character is a consonant c) changeCase() – if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case. Example output is given below: Enter a character a a is a vowel a is not a consonant a is equivalent to A Note: Java represents character using Unicode encoding and ‘A’ to ‘Z’ is represented by numbers 65 to 90 and ‘a’ to ‘z’ is represented by numbers 97 to 122. So to convert ‘A’ to ‘a’ you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer. You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of…arrow_forward
- Task 1: Write a Java Program which will determine whether a number is even or odd. Take the number as an input from the user. Perform the checking in a separate method other than main method. Print the results in main method. Task 2: Find out the area of three geometric shape: Circle, Triangle, Square. Give the user an option to select which geometric shape's area he/she wants to find out. Based on the choice take necessary input and find out the result. Use different area method for each geometric shape. Print the result in main method.arrow_forwardWrite a method that finds the average of 4 double numbers.
