Question

Suppose I have a utility function like this –

public static boolean isABlankSpace(char c)
  {

     // returns true if the char c is rendered as a blank space
  }

My current implementation only does-

if(c == ' ') 
 {
    return true;
 }

But I realize that many other ASCII codes could be rendered as blanks. So which are these ASCII codes? And how would that change my implementation?

Answer 1

You could use:

Character.isWhitespace(c);

which is a built in utility method. Details of what it does is in the javadoc. Note that it will return true for line breaks (\n, \r etc.) too.
