A: String regex = “”;
B: String regex = “ “;
C: String regex = “.*“.
D: String regex = “\\s”
E: String regex = “\\.\\s*”;
F: String regex = “\\w[ \.] +“;
举一反三
- 11. String test = “Test A. Test B. Test C.”; 12. // insert code here 13. String[] result = test.split(regex); Which regular expression inserted at line 12 will correctly split test into “Test A,” “Test B,” and “Test C”?() A: String regex = “”; B: String regex = “ “; C: String regex = “.*“. D: String regex = “\\s” E: String regex = “\\.\\s*”; F: String regex = “\\w[ \.] +“;
- 11. String test = “This is a test”; 12. String[] tokens = test.split(”\s”); 13. System.out.println(tokens.length); What is the result?() A: 0 B: 1 C: 4 D: Compilation fails. E: An exception is thrown at runtime.
- 11. String test = “This is a test”; 12. String[] tokens = test.split(”\s”); 13. System.out.println(tokens.length); What is the result?() A: 0 B: 1 C: 4 D: Compilation fails. E: An exception is thrown at runtime.
- Given: 11. String test = "This is a test"; 12. String[] tokens = test.split("\s"); 13. System.out.println(tokens.length); What is the result?() A: An exception is thrown at runtime. B: 1 C: 4 D: Compilation fails. E: 0

hive里创建表test,表里添加两个字段id和name,以下哪个HQL是正确的( ) A: create test(id int, name string); B: create test(int id, string name); C: create table test(int id, string name); D: create table test(id int, name string)

请阅读下面的程序 class Test { private static String name; static { name = "World"; System.out.print (name); } public static void main(String[] args) { System.out.print("Hello"); Test test = new Test(); } } 下列选项中,程序运行结果是

编写程序将String类型字符串”test” 变为 “tset
- 4
public class Test { public static void main(String[] args) { String s1 = "abc"; String s2 = new String ("abc"); System.out.println(s1 == s2); } } 程序运行结果是
