Does Java JIT compiler remove method's call without side effects? -


i have simple method check if input string valid xpath

private boolean isxpath(string value) {     boolean isxpath = true;     try {         xpath xpath = xpathfactory.newinstance().newxpath();         xpath.compile(value);     } catch (xpathexpressionexception e) {         isxpath = false;     }     return isxpath; }

can sure jit compiler won't remove code inside try block, because of has no side effects? or has (possible exception)?

dead code eliminatino not side-effects, using result of computation. since method returns isxpath, cannot derived without executing try block, impossible jit compiler eliminate it.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
