下面是相应的Java代码: importjava.util.Scanner;publicclassMain{publicstaticvoidmain(String[]args){// 用户输入小写字母Scannerscanner=newScanner(System.in);System.out.print("请输入小写字母:");charlowercase=scanner.next().charAt(0);// 将小写字母转换为大写字母charuppercase=convertToLowercase(lowercase)...
3.然后主函数里面要注意类里面convert用的字符串,而不是字符数组 importjava.util.Scanner;publicclassconvertmain {publicstaticvoidmain(String[] args) {//TODO Auto-generated method stubScanner sc=newScanner(System.in); String [] work=newString[200];for(inti=0;i<work.length;i++) { String test=...
Converts the character (Unicode code point) argument to lowercase using case mapping information from the UnicodeData file.
java中的Character和char的区别如下：数据类型：char是Java中的基本数据类型，用于存储单个字符。Character是Java中的一个类，是char的包装类，用于将基本数据类型封装为对象。内存占用：char作为基本数据类型，直接存储字符值，占用固定的内存空间。Character作为对象，除了存储字符值外，还包含对象头等信息，...
toLowerCase() method is a String class method, it is used to convert given string into the lowercase. toLowerCase()方法是String类方法,用于将给定的字符串转换为小写。 Syntax: 句法: String String_object.toLowerCase(); Here, String_object is a String object which we have to convert into low...
format(template, params); } /** * 下划线转驼峰命名 */ public static String toUnderScoreCase(String str) { if (str == null) { return null; } StringBuilder sb = new StringBuilder(); // 前置字符是否大写 boolean preCharIsUpperCase = true; // 当前字符是否大写 boolean curreCharIsUpperCase =...
An object of class Character contains a single field whose type is char. In addition, this class provides a large number of static methods for determining a character's category (lowercase letter, digit, etc.) and for converting characters from uppercase to lowercase and vice versa. Unicode...
For example, if you pass a primitive char into a method that expects an object, the compiler automatically converts the char to a Character for you. This feature is called autoboxing—or unboxing, if the conversion goes the other way. For more information on autoboxing and unboxing, see ...
