(Intro to Java)explain the answers to the below questions using step-by-step explanation. **Question 1:***Write the below method. Explain all parts of the method thoroughly:***Contains Digit:**- This method must be named `containsDigit`.- It takes a `String` parameter.- It returns a boolean indicating whether there are any numerical digits (0-9) contained in the String.Example:- `containsDigit("123 E. Elm St")` -> `true`- `containsDigit("E. Elm St")` -> `false`*Hint: use the characters '0' and '9' in your answer rather than their Unicode values.*

The given problem is related to Java programming where a function is to be implemented as per the given logical result.Start method that takes one string as parameters Repeat through each character of string IF character is digit Return true If loop ended but function didn't get any digit Return false private static boolean containsDigit(String str) {//returns boolean value and takes string parameter char[] charArray = str.toCharArray();//make an array of characters from passed string for(int i = 0; i<charArray.length; i++) {//repeat for each character in array if(Character.isDigit(charArray[i]))//isDigit() returns true if character is a digit. return true;//if it i a digit, return true }//end for loop return false;//loop ended, but no digit found, return false } If the function is called from below the main method: public static void main(String[] args) { System.out.println("Does ABC123 contains digit: "+containsDigit("ABC123")); System.out.println("Does E. Elm St contains digit: "+containsDigit("E. Elm St")); System.out.println("Does 123 E. Elm St contains digit: "+containsDigit("123 E. Elm St"));} Output will be as follow:
