title: Java regular expression for negative numbers?
body: <p>I have this pattern:</p>
  
  <p><code>Pattern.compile("T([0-9]*)");</code></p>
  
  <p>which works fine for positive numbers but I need it to also do negative numbers for instance "T-1T3T44" should work. Or maybe use space instead of 'T' so it should work for strings like this:"-1 2 3 2 -1 6 2". Sorry I haven't really used regular expressions before.So any suggestions? Thanks.</p>
