Scala Programming: Given string str, write a Scala program to create a new string where "Scala " is added to the front of a given string. If the string already begins with "Scala", return the string unchanged. Otherwise, return the string after adding "Scala ". Test the function for two strings "Scala Programming" and "Programming" inside the main method.

In Programming When you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?

(Intro to Java) Pls answer asap Write Answers Neatly Thanks

Java - Normalizing

1. Write the method named skipChar()* * You are given a String str. Return a new String* where there are two copies of the first character,* no copies of the second, two copies of the third,* and so on.** Examples:* skipChar("hello") returns "hhlloo"* skipChar("cat") returns "cctt"* skipChar("frog") returns "ffoo"** @param str the String to start with* @return a new String as described here*/

Do in Scala language

in c++ code

A String object in Java is considered to be mutable, i.e., the characters it contains can be changed by its methods.  True  False

Write in Java please
