2,String toString():将对象变成字符串;默认返回的格式:类名@哈希值 = getClass().getName() + '@' + Integer.toHexString(hashCode()) 为了对象对应的字符串内容有意义,可以通过复写,建立该类对象自己特有的字符串表现形式。 public String toString(){ return "person : "+age; } 3,Class getClass():...
One way to reverse a string is using recursion. Recursion is the repeated invocation of a method. See the sample code below: publicstaticString reverseStringUsingRecursionSample(String sampleStr){ StringrightString = "";String leftString = "";intlen = sampleStr.length();if(len <= 1)returns...
String类包含用于连接两个字符串的方法: string1.concat (string2相等); 这将返回一个新的字符串,它是string1,末尾添加了string2。 字符串通常与+运算符连接,如in“Hello”+“world”+“! 需要注意的是:当使用字符串的时候,如果超过行大小,则需要+连接比如如下: AI检测代码解析 String quote = "Now is the...
Each such collection has a well-defined first element, second element, and so forth, up to the last element. Provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order. Value: Improves developer productivity by offering a uniform set of ...

reverse:将一个List中的元素反向排列 fill:用指定的值覆写List中的每一个元素,这个操作在重新初始化List时有用 copy:接受两个参数,目标List和源List,将源中的元素复制到目标,覆写其中的内容。目标List必须至少与源一样长,如果更长,则多余的部分内容不受影响。 实例1:使用switch结构计算每个月的天数(考虑闰年) ...
