How do I compare strings in Java? -

i've been using == operator in program compare strings far. however, ran bug, changed 1 of them .equals() instead, , fixed bug. is == bad? when should , should not used? what's difference? == tests reference equality (whether same object). .equals() tests value equality (whether logically "equal"). objects.equals() checks nulls before calling .equals() don't have (available of jdk7, available in guava ). consequently, if want test whether 2 strings have same value want use objects.equals() . // these 2 have same value new string("test").equals("test") // --> true // ... not same object new string("test") == "test" // --> false // ... neither these new string("test") == new string("test") // --> false // ... these because literals interned // compiler , refer same object "test" == "test" // --> true // ... should call objects.equals() o...

java - How much string objects are created (String.format())? -

after dispute colleague couldn't find solution. question for(int = 0; < 2; i++) { string.format("variable = %d", i); } how variables created during running code? have opinion, here can created 4 variables: "variable = %d", "variable = %d" - on both cycle steps created object formatting "variable = 0", "variable = 1" - resulted strings. am right? "variable = %d" string literal, put in string pool , not created twice. hence, you'll have total of 3 strings: "variable = %d" , "variable = 0" , "variable = 1" .

Regex to find a substring with a specific length that contains minimum occurrences of a specific characters -

is there regex find substring specific length contains minimum number of specific char occurrences? for example have string such as: aababaaaaa string have substring length 5 contains 2 b => aabab regex should find it. but aaaabaaaab there not substring length of 5 contains 2 b. suppose our string contains , b , want find substring length of 5 contains @ least 2 b: aaaabaaaab -> invalid aaaaaaaabb -> valid aaaaaaaaaabaabaaaaaa -> valid aaaabaaaaaaabaaaaaaa -> invalid brute force: .b..b|b...b|..bb.|.b.b.|..b.b|bb...|b.b..|...bb|b..b.|.bb.. well, know such regular expression not parametrizable. on other hand it's possible obtain programmatically (the example in python): import itertools def get_regex(char, charnum, strsize): chars = char * charnum + "." * (strsize - charnum) return "|".join("".join(x) x in set(itertools.permutations(chars))) print get_regex("b", 2, 5)
