I have been thinking about how to write a regular expression to determine whether a string is a json array. If I want to write a regular expression, I can't figure out a solution first, check whether it is wrapped by {} or []. The test code is as follows: Pattern pattern = Pattern. compile ("(^ \\[. * \] $ | ^ \\{. * \\}$) {1} "); String s1 =" [aaa] "; // true String s2 =" [aaa "; String s3 =" aaa] "; string s4 = "{aaa}"; // true String s5 = "{aaa"; String s6 = "aaa}"; String

Touch java constant pool and java constant The java constant pool is a persistent topic and the interviewer's favorite. There are a variety of things on the subject. This time, I have heard about the constant pool. Theory The following is a poor description of jvm Virtual Memory Distribution: 1 String s1 = "Hello"; 2 String s2 = "Hello"; 3 String s3 = "El" + "lo "; 4 String s4 = "El" + new String ("lo"); 5 String s5 = new String ("Hello"); 6 String s6 = s5.intern (); 7 String
