由于業(yè)務(wù)，需要經(jīng)常地對數(shù)據(jù)分割，這兩種都是用過，感覺split比StringTokenizer好用，究其原因，split是JDK1.4新功能，彌補(bǔ)了StringTokenizer，因此StringTokenizer也沒更新過了。
public String[] split(String regex);
package com.Gavin.tools;
public class TestSplit 
{
public static void main(String[] args) {
TestSplit ts = new TestSplit();
System.out.println(ts.bubbleSort("1,32,23 14 5,7"));
}
public static String bubbleSort(String str1) {
String st[] = str1.split(",| ");
for (int i = 0; i < st.length; i++) {
for (int j = 0; j < st.length - 1 - i; j++) {
if (Integer.parseInt(st[j]) > Integer.parseInt(st[j + 1])) {
String temp = st[j];
st[j] = st[j + 1];
st[j + 1] = temp;
}
}
}
String str2 = "";
for (int i = 0; i < st.length; i++) {
if (str2.equals("")) {
str2 = st[i];
} else {
str2 = str2 + "," + st[i];
}
}
return str2;
}
}
//1,5,7,14,23,32
public StringTokenizer(String str, String delim);
package com.Gavin.tools;
import java.util.StringTokenizer;
import org.apache.log4j.Logger;
public class TestStringTokenizer {
private static Logger logger = Logger.getLogger(TestStringTokenizer.class);
public static void main(String[] args) {
StringTokenizer tokenizer = new StringTokenizer("I am a developer in shenzhen", " ");
logger.debug(tokenizer.countTokens());
while(tokenizer.hasMoreTokens()) {
logger.debug(tokenizer.nextToken());
// logger.debug(tokenizer.nextToken(" ")); //nextToken(String delim); 下一個分隔符分割的值
}
}
}
