java中的符号计数方法

Question

我正在使用一个程序读取一个文本文件，然后计算数字（大写、小写、空格）。我的问题是，如何将文本的其余部分（数字，“.（）/：；）一起计算

下面是一些代码

for (int b = 0; b < crunchifyLine.length(); b++) {
    if (Character.isUpperCase(crunchifyLine.charAt(b))) {
        UppeLetter++;
    }
}

for (int b = 0; b < crunchifyLine.length(); b++) {
    if (Character.isLowerCase(crunchifyLine.charAt(b))) {
        LowerLetter++;
    }
}

for (int c = 0; c < crunchifyLine.length(); c++) {
    if (Character.isWhitespace(crunchifyLine.charAt(c))) {
        spaceNum++;
    }
}

这不是一个优雅的解决方案，但它仍然适用于您：

final int SPACE_ASCII = ' ';
    final int UPPER_CASE_LOWER_ASCII_LIMIT = 'A';
    final int UPPER_CASE_UPPER_ASCII_LIMIT = 'Z';
    final int LOWER_CASE_LOWER_ASCII_LIMIT = 'a';
    final int LOWER_CASE_UPPER_ASCII_LIMIT = 'z';
    final int DIGIT_LOWER_ASCII_LIMIT = '0';
    final int DIGIT_UPPER_ASCII_LIMIT = '9';
    final String OTHER_CHARS = "\". ' ()/ :;";

    int uppercaseCount = 0;
    int lowercaseCount = 0;
    int whitespaceCount = 0;
    int otherSymbolsCount = 0;
    int discardedSymbolsCount = 0;

    String text = "$Your String Goes here. 123#";

    for (int i = 0; i < text.length(); i++) {
        Character c = text.charAt(i);
        if (c == SPACE_ASCII) {
            whitespaceCount++;
        } else if ((c >= DIGIT_LOWER_ASCII_LIMIT && c <= DIGIT_UPPER_ASCII_LIMIT)
                || OTHER_CHARS.contains(String.valueOf(c))) {
            otherSymbolsCount++;
        } else if (c >= UPPER_CASE_LOWER_ASCII_LIMIT && c <= UPPER_CASE_UPPER_ASCII_LIMIT) {
            uppercaseCount++;
        } else if (c >= LOWER_CASE_LOWER_ASCII_LIMIT && c <= LOWER_CASE_UPPER_ASCII_LIMIT) {
            lowercaseCount++;
        } else {
            discardedSymbolsCount++;
        }
    }

    System.out.println("White Space : " + whitespaceCount);
    System.out.println("Upper Case : " + uppercaseCount);
    System.out.println("Lower Case : " + lowercaseCount);
    System.out.println("Others : " + otherSymbolsCount);
    System.out.println("Discarded : " + discardedSymbolsCount);

基于“部分代码”，我将其更改为更类似于：

for (int b = 0; b < crunchifyLine.length(); b++) {
    if (Character.isUpperCase(crunchifyLine.charAt(b))) {
        UppeLetter++; // [sic]
    } else if (Character.isLowerCase(crunchifyLine.charAt(b))) {
        LowerLetter++;
    } else if (Character.isWhitespace(crunchifyLine.charAt(c))) {
        spaceNum++;
    } else {
        restOfTheTextTogether++;
    }
}

另一种方法是：

restOfTheTextTogether = crunchifyLine.length() -
    UppeLetter /*[sic]*/ - LowerLetter - spaceNum;

同样对于样式，您混合了以小写字母开头的变量和以大写字母开头的变量，您可以看到the automatic syntax highlighter标记通常意味着不同的东西（尽管这只是惯例）
