Use Java Programming;   You are tasked to make a program that accepts a string. From that string, print out the number of permutations and all the permutations of that string including itself.   Expected output: String: abc   All permutations of abc: 6 abc acb bac bca cab cba
Suppose s is a string with the value "java". What will be assigned to x if you execute the following code? char x = s.charAt(4);

  • An expression using the `+' operator in Java produces : (a String expressing the sum of the operands, if they are numbers of different types? the sum of the left and right operands, provided they are numbers of the same type? a concatenation of the left and right operands, provided they are both Strings? a String representation joining the left and right operand, if they are numbers of different types? a String concatenation if one of the operands is non-numeric? ) . The operator also offers a convenient way to turn any value or object into its String representation. This involves specifying :( the object as the right operand and null as the left operand? the object as the right operand only? the object as the left operand only? the object as right operand and the empty string as the left operand? the object as one operand and the empty string as the other?)

    3. Write a Java program that takes the user to provide a single character from the alphabet. Print Vowel or Consonant, depending on the user input. If the user input is not a letter (between a and z or A and Z), or is a string of length > 1, print an error message.4. Write a program in Java to input 5 numbers from keyboard and find their sum and average.
    In Java, Write a program that prompts the user to enter a full name consisting of three names (first middle last) into one String variable. Then use methods of class String to: print the number of characters in the full name, including spaces print just the middle name and the number of characters in it. print the three initials of the name print the last name in all upper case. print the full name in the usual alphabetical format (last, first middle) and proper case.
  • I'm having trouble getting my problem to display correctly in java. I want the final message to show up in one dialog window Joptionpane but its give me each and every word seperately. How would I fix this to the phrase and then each word that was initally entered?   for (String pigLatin : arr) {output = String.format(pigLatin.substring(1) + pigLatin.substring(0, 1) + "ay ");JOptionPane.showMessageDialog(null, "The phrase you entered translates to:\n" + output);
    PLEASE HELP ME FIND THE JAVA CODE FOR THIS PROBLEM   4. Is It You, Cody? by CodeChum Admin Can you identify if Cody's name is spelled right? If so, then make a program that accepts four one-letter strings separated by space and print "Correct" if the inputted strings, combined in order, spell the name Cody correctly. If not, print "Wrong". It doesn't matter if it's in uppercase or lowercase, as long as it's spelled correctly, it's considered correct.   Now, will you take on this task? Input A line containing four one-letter strings separated by a space. c·O·D·y Output A line containing a string. Correct
    I need help with this Java problem as it's explained in the image below:  Palindrome (Deque) A palindrome is a string that reads the same backwards and forwards. Use a deque to implement a program that tests whether a line of text is a palindrome. The program reads a line, then outputs whether the input is a palindrome or not.   Ex: If the input is: senile felines!   the output is: Yes, "senile felines!" is a palindrome.     Ex: If the input is: rotostor   the output is: No, "rotostor" is not a palindrome.   Ignore punctuation and spacing. Assume all alphabetic characters will be lowercase. Special case: A one-character string is a palindrome. Hint: The deque must be a Deque of Characters, but ordinary chars will be automatically converted to Characters when added to the deque.   Java Code:    import java.util.Scanner; import java.util.LinkedList; import java.util.Deque; public class LabProgram {      public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);…
