云南大学软件学院Java试验四

1、姓名： 王定欢 学号：188 班级： 日期： 成绩：JAVA实验四一、实验目的：Fundamental Programming Structures in Java： Strings二、实验要求：1 Write a program called and do the following：2. Create a String object that accepts input from the userReferencing the JDK docs,execute 2 different methods on the StringPrint the results of the methods

2、3 Write a program called that does the following：4. Create a StringBuffer object Referencing the JDK docs, execute 2 different methods on the StringBuffer Print the results of the methods5. Write a program called that accepts a string, looks for commas within the string, andbreaks the string up into

3、 the parts separated by the commaFor example, the stringKunming, Yunnan, China would return three strings：6. Stringl = Kunming7. String2 = YunnanR8. String3 = China*三、实验内容：1、代码：package lab4；import class Stringl ；public static void main(String args)Hplease input a string1)；Scanner _in = new Scan net；

4、String in put =():the in put string is十 input)；please input a stringthis is a stringthe input string is:this is a stringthe uppercase string is:THIS IS A STRINGthe string length is:16()；ppend(nworldM)；String T;i) (i;逆序为:+rs)；实验结果：please input a string with commas: kunmingf yunnan,china|stringl=kunmi

5、ngString2=yunnanString3=china逆序为；anihcf nannuyA gnimnuk4.附加题：代码：package lab4；import class lab4 public static void main(Stringargs)String name = new String(*My name is 1 ilei；the length of string is：*+()；char firstChar = (0) ；/第一个位置the first char is：irstChar)；*the last char is： +()T) ；/最后一个位置Str in gTokenizer str = new StringTokenizer (name, * ”)； the first world is： *+()；String】 strl = C ”)； /7找出 lilei的位置 int length =;the place of LiLei is： M+length)；.实验结果the length of string is:16 the first char is:Mth巳 last char is:ithe
