public MyString2(String s);
public int compare(String s);
public MyString2 substring(int begin);
public MyString2 toUpperCase();
public char[ ] toChars();

Method Details
addDelimiter:
public static java.lang.String addDelimiter(java.lang.String str, char delimeter)
Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++.
Parameters:
str -
delimeter -
Returns:
String with characters…
PROBLEM STATEMENT:
Use string interpolation to insert "INSERTED" into to the parameter str!
public class StringInterpolation{public static String solution(String str){// ↓↓↓↓ your code goes here ↓↓↓↓return null;.

- Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.arrow_forwardProblem 2: Complete the seperateDuplicateChars () method in Seperate Duplicates.java as follows: The method takes a String str as a parameter and returns a new String. The returned String should be exactly like str, but any identical characters that appear in a consecutive way must be separated by hyphens "-". You may ONLY use the following methods from the String class: charAt(), substring() and length(). Other than uncommenting the code, do not modify the main method in Seperate Duplicates.java. Sample runs provided below. Argument String str "Hello" "Bookkeeper" "Yellowwood door" "Chicago Cubs" Return String "Hel-lo" "Bo-ok-ke-eper" "Yel-low-wo-od do-or" "Chicago Cubs"arrow_forward3. how can reverse numbers in a string when they are split with "-"?

The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below.

- Complete the method in Java. Name of the public class is Assignment1.javaarrow_forwardWrite the following programs in Java: In the Converter class write the static method, bin2decimal(String bin). The parameter for this method is an unsigned (nonnegative) binary number represented by a string. The method returns the decimal equivalent for the binary parameter, as an integer.If the binary string is invalid (contains characters other than ‘0’ and ‘1’), the method returns -1. Convert from a binary (b) string with up to 16 digits to decimal (d) using the following formula:? = ?0 + ?1 × 2 + ?2 × 22 +⋯+ ?7 × 215where b0, b1, ?2, … ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 + 0×2 + 1×22 + 1×23 = 13 in decimal. Side note: You may NOT use the decode method of the Long wrapper class instead of this formula. In the Converter class write another static method, english2encrypted(String english). The parameter for this method is a word or sentence represented by a string. The word or sentence should only contain letters (no digits,…arrow_forwardWrite a recursive method that displaysa string reversely on the console using the following header: public static void reverseDisplay(String value) For example, reverseDisplay("abcd") displays dcba.
