Java 字串分開的方法

用split

String test = "It's a dog.";
String[] testSplit = test.split(" "); 

for ( int i = 0 ; i < testSplit.length ; i++ ){ 

     System.out.println(testSplit[i]);

     System.out.println("\n");

} 

印出

It's

a

dog.

用token

String ori1 = "I am a good man.";

StringTokenizer st1 = new StringTokenizer(ori1);

while (st1.hasMoreTokens()) {
         System.out.print(st1.nextToken());
         System.out.print('\n')

} 

印出

I

am

a 

good

man

用 scaner

String ori1 = "I am a good man.";

Scanner tokenize = new Scanner(ori1);

while (tokenize.hasNext()){
  System.out.print(tokenize.next());
  System.out.print("\n");

}

印出

I

am

a 

good

man

除了split可以任意指定要分隔的字元。

token 和 scanner 都只能分隔空白鍵。
