在上面的代码中,我们使用Character.isLetterOrDigit(c)和Character.isWhitespace(c)方法来判断字符是否为字母、数字或空格,如果不是,则将hasSpecialChar标记为true,并跳出循环。 步骤三:输出结果 最后,我们根据hasSpecialChar的值输出结果。 if(hasSpecialChar){System.out.println("The string contains special characte...

A character may start a Java identifier if and only if one of the following conditions is true: #isLetter(char) isLetter(ch) returns true #getType(char) getType(ch) returns LETTER_NUMBER ch is a currency symbol (such as '$') ch is a connecting punctuation character (such as...
In the Java programming language char values represent Unicode characters. If you check the properties of a char with the appropriate Character method, your code will work with all major languages. For example, the Character.isLetter method returns true if the character is a letter in Chinese, ...

This is what the 这就是 cannot find symbol 1. error message is saying—the compiler doesn't have enough information to piece together what the Java code is intended to execute. 错误消息说-编译器没有足够的信息来拼凑Java代码打算执行的内容。

read()将字符返回为0到65535之间的一个int(Java中的一个char可以被视为一个无符号的16位整数); 如果检测到end-of-stream,则为-1。 read()还有两个变量可以将一个字符块读入char数组。 代码语言:javascript 复制 publicabstract intread()throws IOExceptionpublicintread(char[]chars,int offset,int length)throw...
