接着调用reverse()方法将字符串反转,最后通过toString()方法获取反转后的字符串,并输出结果。 类图 下面是StringBuffer类的类图: Class01int countint value[]StringBuffer+StringBuffer()+append()+insert()+delete()+reverse() StringBuffer反转字符串的过程 通过上面的示例,我们可以简单认识了StringBuffer类的reverse...

但是今天在查看StringBuffer源代码的时候发现,其中reverse方法的源代码写的很精妙。源代码如下: 1 public AbstractStringBuilder reverse() { 2 boolean hasSurrogate = false; 3 int n = count - 1; 4 for (int j = (n-1) >> 1; j >= 0; --j) { 5 char temp = value[j]; 6 char temp2 = ...

reverse()是属于类StringBuffer的一个方法 你在使用StringBuffer这个类之前要先导入他的类库。在代码顶部，package语句下面加一句话：import java.lang.StringBuffer;
// After creating the object, you can reset values of the value field by calling setNewValue(int) method. // This is a mutable class. public class MutableClassExample { private int value; public MutableClassExample(int value) { this.value= value; ...
Let n be the character length of this character sequence (not the length in char values) just prior to execution of the reverse method. Then the character at index k in the new character sequence is equal to the character at index n-k-1 in the old character sequence. Note that the ...
