- Follow these steps: Open the Java file Errors.java. Attempt to compile the program. You'll notice the compilation will fail due to some errors. Fix all the compilation errors and compile the program again. Every time you fix an error, add a comment to the line you fixed and indicate which of the three types of errors it was. Now run the program. Once again, you'll encounter some errors (this time, runtime errors). Fix these errors and run the program once again to see if it works. Now run the program and notice the output. You'll notice that there are some logical errors in the code. Fix these errors and run the program once again to see if it now correctly displays what it should.arrow_forwardPROBLEM STATEMENT: An anagram is a word that has been rearranged from another word, check tosee if the second word is a rearrangement of the first word. public class AnagramComputation{public static boolean solution(String word1, String word2){// ↓↓↓↓ your code goes here ↓↓↓↓return true;}} Can you help me with this java question the language is java please use the code I gavearrow_forwardclass Output{public static void main(String args[]){Integer i = new Integer(557);float x = i.floatValue();System.out.print(x);}} What will the given code prints on the output screen.arrow_forward
