}


/*Result
--------------------Configuration: <Default>--------------------
s1.length = 7
s1.startWith fan = true
s1.endWith fan = false
s1.charAt(4)=a
before is:select x from x where id=x
replace:select table from table where id=table
replaceFirst:select table from x where id=x
replaceAll:select table from table where id=table

Process completed.
