Learn to write asimple Java program that finds the duplicate characters in a String. This can be a possibleJava interview questionwhile the interviewer may evaluate our coding skills. We can use the given code tofind repeated charactersor modify the code tofind non-repeated characters in the s...
Largely, the process to find the duplicates using Collections is simlar to previous approach. We start with splitting the string and collecting all words in aList. Then we use theHashSet.add()method to check if the word is unique or duplicate. List<String>wordsList=Arrays.asList(sentence.s...

String.hash32()不是public的,所以我不得不查看了下HashMap的内部实现,来找到怎么调用这个方法,答案就是sun.misc.Hashing.stringHash32(String)。 The same test on 1 million distinct keys has shown 304 duplicate hash values, compared to no duplicates while using String.hashCode. ...
