Java 实例 – 字符串分隔(StringTokenizer)
Java 中我们可以使用 StringTokennizer 设置不同分隔符来分隔字符串,默认的分隔符是:空格、制表符(\t)、换行符(\n)、回车符(\r)。
以下实例演示了 StringTokennizer 使用空格和等号来分隔字符串:

JavaStringSplitEmp.java 文件
import java.util.StringTokenizer;
public class Main {
public static void main(String[] args) {
StringTokenizer st = new StringTokenizer(str);
while (st.hasMoreElements()) {
System.out.println(st.nextElement());
}
StringTokenizer st2 = new StringTokenizer(str, ",");
System.out.println(st2.nextElement());
}
}
}
public static void main(String[] args) {
String str = "This is String , split by StringTokenizer, created by runoob";
StringTokenizer st = new StringTokenizer(str);
System.out.println("—– 通过空格分隔 ——");
while (st.hasMoreElements()) {
System.out.println(st.nextElement());
}
System.out.println("—– 通过逗号分隔 ——");
StringTokenizer st2 = new StringTokenizer(str, ",");
while (st2.hasMoreElements()) {
System.out.println(st2.nextElement());
}
}
}
输出结果:
----- 通过空格分隔 ------ This is String , split by StringTokenizer, created by runoob ----- 通过逗号分隔 ------ This is String split by StringTokenizer created by runoob
