java - Regex to replace all leading characters not a-Z -


i need replace non-letter characters appear @ start before letter example

$ %5hello w8r^ld becomes hello w8r^ld

this regex got works greate replacing none word characters not replace numbers

s.replacefirst("^[\\w_]+", "")

you using wrong character class. use

s.replacefirst("^[^a-za-z]+", "")

that is

^          start @ beginning of string [^  ]+     1 or more (greedy - keep going until hit letter a-za-z     ascii characters between a-z or a-z

following comments @anubhava, changed * +. if have no match, there nothing needs replacing. it's cleaner.

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
