Shouldn't it be \\d\\d instead of \d\d in the question?

[admin]

No, \\ is required only when you specify the \d in java code.

HTH,

Just a question in proper code standards.

The code

Code: Select all

Pattern p = Pattern.compile(args[0]);
	Matcher m = p.matcher(args[1]);
	boolean b = false;
	while(b = m.find())
	{
	    System.out.println(m.start()+" "+m.group());
	}

Is actually setting in the while loop constantly the b.

Is it not better code use to do the following?

Code: Select all

Pattern p = Pattern.compile(args[0]);
	Matcher m = p.matcher(args[1]);
	
	while(m.find())
	{
	    System.out.println(m.start()+" "+m.group());
	}

[admin]

Yes, it would be better
