我正在开发一个 CLOC 程序，它遍历其他程序的源代码并从中获取值！，其中它使用以下方法将一些值保存到 CSV 文件中：
out.write
问题是，我运行程序的次数与将写入文件中的值一样多，不管它们是否已经存在！
我的问题是如何告诉程序只写不可用的值！
这是我的代码：
private void writeReport() {
BufferedWriter out = null;
try {
File file = new File("out.csv");
boolean exists = file.exists();
FileWriter fstream = new FileWriter(file, exists /*=append*/);
out = new BufferedWriter(fstream);
if (!exists) {
out.write("Project Name;");
out.write("Version;");
out.write("Download Date;");
out.write("Total Lines of Code;");
out.write("Executable Lines;");
out.write("Lines of Comments;");
out.write("Trivial Lines;");
out.write("Empty Lines;");
out.write("Code Complexity;");
out.write("Number of Files;"); //to be changed to numver of files
out.write("Average File Complexity;"); //to be changed to averag file complexity
out.write("Total Comment Percentage;"); //total
out.write("Total Lines of Test Code;");
out.write("Excutable Test Lines;");
out.write("Lines of Comments in Tests;");
out.write("Trivial Lines in Tests;");
out.write("Empty Lines in Tests;");
out.write("Number of Test Files;");
out.write("Comment Presentage in Test;");
out.write(System.getProperty("line.separator"));
}
// for (int i = 0; i < newFiles.getNrOfFiles(); i++) {
// out.write("test" + ";");
// out.write(newFiles.getParser(i).getSourceFile().getName()+ ";");
out.write(String.valueOf(newFiles.getProjectName()) + ";");
out.write(String.valueOf(newFiles.getVersionNumber()) + ";");
out.write(String.valueOf(newFiles.getDownloadDate()) + ";");
out.write(String.valueOf(newFiles.sumLinesOfCode()) + ";");
out.write(String.valueOf(newFiles.sumLinesOfStatements()) + ";");
out.write(String.valueOf(newFiles.sumLinesOfComments()) + ";");
out.write(String.valueOf(newFiles.sumTrivialLines()) + ";");
out.write(String.valueOf(newFiles.sumEmptyLines()) + ";");
out.write(String.valueOf(newFiles.sumComplexity()) + ";");
out.write(String.valueOf(newFiles.getNrOfFiles()) + ";");
out.write(String.valueOf(newFiles.sumAvgComplexity()) + ";");
out.write(String.valueOf((100 * newFiles.sumLinesOfComments()) / newFiles.sumLinesOfCode() + "%") + ";");
out.write(String.valueOf(testFiles.sumLinesOfCode()) + ";");
out.write(String.valueOf(testFiles.sumLinesOfStatements()) + ";");
out.write(String.valueOf(testFiles.sumLinesOfComments()) + ";");
out.write(String.valueOf(testFiles.sumTrivialLines()) + ";");
out.write(String.valueOf(testFiles.sumEmptyLines()) + ";");
out.write(String.valueOf(testFiles.getNrOfFiles()) + ";");
out.write(String.valueOf((100 * testFiles.sumLinesOfComments()) / testFiles.sumLinesOfCode() + "%") + ";");
out.write(System.getProperty("line.separator"));
// }
//Close the output stream
out.close();
} catch (Exception e) {
System.err.println("Error: " + e.getMessage());
// return;
}
}
那么，我该怎么做呢？
