SCJP題庫第177題
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. 0
B. 1
C. 4
D. Compilation fails.
E. An exception is thrown at runtime.
Ans: D
解說:
\s倒斜線是表示逸出字元,在C/Java裏沒有定義\s這個逸出字元,程式改成:
class test{
public static void main(String[] args) {
String test = "This is a test";
String[] tokens = test.split(" ");
System.out.println(tokens.length);
}
}
