我的程序会编译并写入一个.txt文件,但是它只会写入最后一个数据集大小1000。我正在尝试将其所有十个大小都写入一个.txt文件。如果我不使用PrintSteam方法,则完整的输出将包括所有十个数据集。我将如何使十个人全部写入.txt文件?下面是主要代码和BenchmarkSorts类中写入文件的部分。
import java.io.IOException;
import java.io.FileNotFoundException;
public class SortMain {
public static void main(String[] args) throws Exception, IOException, FileNotFoundException {
int[] sizes = {100, 200, 300, 400, 500, 600, 700, 800, 900, 1000};
new BenchmarkSorts(sizes);
}
}
try {
// Creating a File object that represents the disk file.
PrintStream o = new PrintStream(new File("BenchmarkSort.txt"));
// Store current System.out before assigning a new value
PrintStream console = System.out;
// Assign o to output stream
System.setOut(o);
// Produces output
System.out.println("Data Set Size (n): " + arraySize +
"\n\tIterative Selection Sort Results: \t\t\t\t\tRecursive Selection Sort Results:" +
"\n\tAverage Critical Operation Count: " + Math.round(iterativeAverageCount) +
"\t\t\tAverage Critical Operation Count: " + Math.round(recursiveAverageCount) +
"\n\tStandard Deviation of Count: " + Math.round(iterativeSDCount) +
"\t\t\t\t\tStandard Deviation of Count: " + Math.round(recursiveSDCount) +
"\n\tAverage Execution Time: " + Math.round(iterativeAverageTime) +
"\t\t\t\t\t\tAverage Execution Time: " + Math.round(recursiveAverageTime) +
"\n\tStandard Deviation of Time: " + Math.round(iterativeSDTime) +
"\t\t\t\t\t\tStandard Deviation of Time: " + Math.round(recursiveSDTime));
// Use stored value for output stream
System.setOut(console);
System.out.println("Output File is now BenchmarkSort.txt");
}
catch(FileNotFoundException ex) {
}
实际上,这已覆盖每个文件。尝试按日期指定唯一的文件名,然后检查newDate()。getTime();
