java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".

/** * Processing Data with Loops */ public class oddSum { /** Write the method named oddSum(); * * Given a String str return the arithmetic sum of the odd-numbered digits '1'-'9' that appear in the string, ignoring all other characters. Return 0 if there are no digit characters in the string. * * * * You cannot use any of the classification method in the Character class. You must use the relational operators and simple logic to decide if a character is a digit. To convert a digit character to a binary number, simply * subtract the character '0'. * Examples: oddSum("aa1bc2d3") returns 4 (2 is even) oddSum("aa11b33") returns 8 oddSum("") returns 0 @param str the String search for digits @return the sum of the digits odd digits * / public int oddSum(String str) { // Complete the oddSum method here * * .. }

Intro to Java Instuctions: Design and implement a program that reads a series of 10 integers from the user and prints their average For each of the 10 numbers input from the user: one at a time, prompt the user to enter a number. Then read input from the user as a string. Attempt to convert it to an integer using the "Integer.parseInt" method. If the process throws a "NumberFormatExeption", print an appropriate error message and prompt the user for the number again. Continue prompting and reading in number until 10 valid integers have been read Print "The average is" and then print the average of the 10 numbers Code: import java.util.Scanner; public class Lab1MainClass { public static final int VALUES_TO_READ = 10; public static void main(String[] args) { // local variables int[] values = new int [VALUES_TO_READ]; double average; Scanner scan = new Scanner(System.in); int values Read = 0; // how many numbers the user has given us, a count of where we are String userInput; // read…

JAVA Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You have solved a similar problem in a previous lab using a while loop.   You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. You also need to count the number of tries and report the count at the end. Use a do-while loop to prompt the user to guess again if the guess is wrong. Make sure that it doesn't mess up the output if you guess the secret number on the first try.…
