四、反转字符串 StringBuffer 类中的 reverse() 方法用于将字符串序列用其反转的形式取代,该方法主要作用就是利用StringBuffer的reverse方法对字符串反转: StringBuffer sb = new StringBuffer("java"); sb.reverse(); System.out.println(sb); // 输出:avaj 1. 2. 3. 五、删除字符串 1、delete方法 delete...
String类是不可变类,即一旦一个String对象被创建后,包含在这个对象中的字符序列是不可改变的,直至这个对象销毁。 StringBuffer类则代表一个字符序列可变的字符串,可通过append、insert、reverse、setChartAt、setLength等方法改变其内容。一旦生成了最终的字符串,调用toString方法将其转变为String StringBuffer:JDK1.0开始 ...

Buffer对象中分别追加String类型、char类型和StringBuffer类型的数据,打印StringBuffer对象,调用delete(int start, int end)方法将指定范围的内容删除,在本例中指定索引为“5,6”,也就是将字符串中间的空格删除了,然后调用insert(int offset, String str)方法在刚删除的空格位置加上“——”,最后调用reverse()方法将...
