该博客展示了一段Java代码，通过StringTokenizer类实现字符串反转功能。定义了分隔符，在reverse方法中对输入字符串进行处理，最后在testReverse方法里对多个句子进行反转测试，并在main方法中调用测试方法输出结果。

import java.util.StringTokenizer;

public class Test{

public static final String SEPARATORS = " ,/t:'';?!";

    public static String reverse(String input){

        StringTokenizer st = new StringTokenizer(input, SEPARATORS, true);
        StringBuffer words = new StringBuffer("");
        while (st.hasMoreTokens()) {
            words.insert( 0, st.nextToken() );
        }
        return words.toString();
    }

    public void testReverse(){

        String[] sentences = new String[]{
            "Hello, world!",
            "I am a student",
            "Am I a student? yes, or no",
            "Am I a student ? yes , or no",
            "Zhuang says:'It's just a coding game.'"
            };

        for (int i = 0; i < sentences.length; i++)
            System.out.println("Sentence[" + i + "]=[" + sentences[i]+"], " +
                "After reversed: [" + Test.reverse(sentences[i])+"]");

    }

    public static void main(String[] args){
        new Test().testReverse();
    }


}
