In Java, isn't a String an object? When I pass a String from method A to void method B as a parameter and assign the String to a different string literal, the value of String in method A is unchanged! Why is that?

In the below example, how many String Objects are created?

What is Modifying StringBuffer Objects?

javaaa Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned. Imagine you are developing a software package for an online shopping site that requires users to enter their own passwords. Your software requires that users’ passwords meet the following criteria: The password should be at least six characters long. The password should contain at least one uppercase and at least one lowercase letter. The password should have at least one digit. Write a program that asks the user to enter a password, then displays a message indicating whether it is valid or not.

Computer Science c# EXTEND Biglnteger with a method named ToWords that returns a string describing the number, for example, 18,000,000 would be eighteen million, and 18,456,000,000,000,000,000 would be about eighteen and a half quintillion.

In some cases, a class depends on itself. That is, an object of one class interactswith another object of the same class. To accomplish this, a method of the classmay accept as a parameter an object of the same class.The concat method of the String class is an example of this situation. Themethod is executed through one String object and is passed another String object as a parameter. Here is an example:str3 = str1.concat(str2);The String object executing the method (str1) appends its characters to thoseof the String passed as a parameter (str2). A new String object is returned asa result and stored as str3. Write java code to implement given conditions

Mariam has a habit to forgot capitalising the first letter of every word in a string having multiple words. Help Mariam by writing a javascript function that takes the string parameter and capitalises the first letter of every word in the string. Test the function on the string given below: "JavaScript program to capitalise first letter of each word in a string."

Add a static method, public static void changeLetter (StringBuilder sb, char letter) Convert all occurrences of the letter variable in the StringBuilder to upper case. Write in java and use test case example as reference.

Design a program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as : enter a string rizma This string has all the unique characters would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique Your code should work for all strings and essentially all characters, as many examples will be tested.
