Java program to check word or phrase is anagram or not

An anagram is a word or phrase made by transposing the letters of another word or phrase; for example "parliament" is an anagram of "partial men" and "software" is an anagram of "swear oft".

Write a program that figures out whether one string is an anagram of another string. The program should ignore white space and punctuation.

import java.util.*;
class Anagram
{
    public static void main(String arr[]) 
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter String 1");
        String str1=sc.nextLine();
        System.out.println("Enter String 2");
        String str2=sc.nextLine();
        boolean flag=true;
        for(int a=0;a        {
            if(str2.indexOf(str1.charAt(a))==-1 && str1.charAt(a)!=' ')
            {
                flag=false;
                break;
            }
        }
        if(flag==true)
        {
            System.out.println("String "+str1+" is anagram of "+str2);
        }
        else
        {
             System.out.println("String "+str1+" is not a anagram of "+str2);
        }
    }
}
