1)- Modify the following code to read character from keyboard 2)- What is the output of following code if ch is 65? public class ASCII { static public void main(String[] args)[ char ch = 65; //the 65 convert to ASCII character if (ch >= 48 && ch <= 58) } System.out.println("You enter a Digit"+ch+"\n"); else if (ch >= 'A' && ch <= 'Z'||ch >= 'a' && ch <= 'z') System.out.println("You enter a alphabet:"+ch+"\n"); else System.out.println("other character:"+ch); ] // write your code on the following window. Question 18 Assume the following: 2 pts • temperatures[] is an array of SIZE elements of type double that has been declared and initialized ⚫ threshold is a variable of type double that has been declared and initialized Write code to do the following • Create and initialize a variable named count to keep track of the number of values in temperatures[] array that are greater than threshold ⚫ Using a for loop, count the number of values in the array temperatures[] that are greater than threshold, and ⚫ Output the count to the console. Edit View Insert Format Tools Table 12pt Paragraph BIUA 2 > р O words </> Question 19 2 pts The formula to compute the volume of a sphere is volume (4/3)лг^3 where r is the radius of the sphere and л is 3.14159. Assume a variable radius has already been declared (type double) and initialized with the value of the radius of a sphere. Write a java method statements to do the following: Declare a constant Pl and initialize it to 3.14159 Declare a variable volume of type double Calculate the volume of the sphere and store it in the variable volume. Your program should return the result to main and display the computed volume on the console. Type in your answer on blow page.
