JAVA Program to Check whether a String is Anagram or not.(Removing white space and making case-insensitive)

Before moving on to code solution. Let us look what Anagram is:

Anagram: Two words are anagrams of one another if their letters can be rearranged to form the other word.

  //program to check whether two strings are anagrams or not.
  import java.util.Arrays;
  public class ANAGRAMS
  {
  public static void main(String args[])
  {
  String x = "ShE iS Madam";
  String y = "iS seh mADam";
  //replacing White spaces
  x=x.replaceAll("","");
  y=y.replaceAll("","");
  //Making cases similar
  x=x.toUpperCase();
  y=y.toUpperCase();
  //converting to array. char is datatype of array
  char a[] = x.toCharArray();
  char b[] = y.toCharArray();
  //now sorting them
  Arrays.sort(a);
  Arrays.sort(b);
  
  Boolean result=Arrays.equals(a,b);
  
  if(result==true)
  {
  System.out.println("Strings are Anagram.");
  }
  else
  {
  System.out.println("Strings are not Anagram.");
  }
  }
  }
  
  

Output:

Strings are Anagram.
