Question

LAB: Convert to binary - methods

Write a program that takes in a positive integer as input, and outputs a string of 1's and O's representing the integer in binary. For an integer X, the algorithm is:
As long as x is greater than 0
Output x 2 (remainder is either 0 or 1)
x = x/ 2
Note: The above algorithm outputs the O's and 1's in reverse order. You will need to write a second function to reverse the string
Ex: If the input is:
6
the output is:
110
Your program must define and call the following two methods. The method integerToReverseBinary should return a string of 1's and O's representing the integer in binary (in reverse). The method reverseString should return a string representing the input string in reverse.
public static String integerToReverseBinary(int integerValue)
public static String reverseString(String inputString)
Note: This is a lab from a previous chapter that now requires the use of a method.

6.34 LAB: Acronyms
An acronym of the input. If a word begins with a lower case letter, dont include that letter in the acronym. Assume there will be at least one upper case letter in the input.
Ex: If the input is:
Institute of Electrical and Electronics Engineers
the output should be:
IEEE
Your program must define and call a method thats returns the acronym created for the given userPhrase. public static String createAcronym(String userPhrase)
Hint: Refer to the ascii table to make sure a letter is upper case.

Answer 1

import java.util.Scanner;

public class Lab{

public static String integerToReverseBinary(int number)

{

String binary = "";

if(number == 0){

return "0";

}

while(number > 0)

{

int remainder = number % 2;

number = number / 2;

binary += Integer.toString(remainder);

}

return binary;

}

public static String reverseString(String wordString)

{

String binaryString = "";

int length = wordString.length();

for(int i = length -1 ; i >= 0 ; i--)

{

binaryString += wordString.charAt(i);

}

return binaryString;

}

Step-by-step explanation:

In the java source code, the Lab class is defined which has two methods, 'reverseString' and 'integerToReverseBinary'. The latter gets the argument from the former and reverses the content of its string value, then returns the new string value. The former gets the integer value and converts it to its binary equivalence for which are converted to strings and returned.
