This is a snippet to validate anagrams of 'debit card'. It validates 'debit card' and 'bad credit'

//regular expression
String patternStr = "(?=.*d.*d)(?=.*e)(?=.*b)(?=.*i)(?=.*t)(?=.*\s)(?=.*c)(?=.*a)(?=.*r)^..........$";
boolean b;
Matcher matcher;
Pattern pattern;
 
System.out.println("Regex pattern = "+patternStr);
pattern = Pattern.compile(patternStr);//compiles the regex
 
//validates bad credit
System.out.println("Validating: bad credit");
matcher = pattern.matcher("bad credit");
b = matcher.matches();
if(b) System.out.println("bad credit: matched");
else System.out.println("bad credit: not matched");
 
//validates debit card
System.out.println("Validating: debit card");
matcher = pattern.matcher("debit card");
b = matcher.matches();
if(b) System.out.println("debit card: matched");
else System.out.println("debit card: not matched");
