我希望将结果保存在文件中,并使用递归方法重写对象并保存任何内容。 如果我尝试申报的PrintWriter globaly那么它给我的错误“默认构造函数不能处理由隐式超级构造函数抛出的异常类型UnsupportedEncodingException。必须定义一个明确的构造函数” 这里是代码在java中编写文件问题
public void lengthFind() {
try {
writer = new PrintWriter("Results.txt", "UTF-8");
fileStreamTest obj = new fileStreamTest();
Scanner s = new Scanner(new File(path));
int max = 0;
while (s.hasNextFloat()) {
int d = (int) s.nextFloat();
// it filters the time stamp
if (d <= 5000) {
String code = obj.GolombCoding(d, dival);
// finding Max length
if (code.length() > max) {
max = code.length();
}
}
}
// Dividend Limit check or increase the Dividend
if (dival == 10) {
writer.println("Divident has reached it Limit !");
i++;
// update the file name
path = "D:/File Compression/Data/low_freq/low_freq/house_1/channel_"
+ i + ".dat";
dival = 10;
} else {
dival = dival + 10;
writer.print("Dividen:" + dival);
}
writer.print("Max Length of File " + i + ": " + max);
writer.println("Path Of the File : " + path);
int counter = 1;
// recall the method
writer.println("Method Call Counter" + counter);
lengthFind();
} catch (IOException e) {
writer.close();
System.out.println("There is no more File");
System.exit(0);
}
什么是不确切的?你有没有看过[UnsupportedEncodingException的javadoc](http://docs.oracle.com/javase/7/docs/api/java/io/UnsupportedEncodingException.html)?你叫什么“全球声明”? – fge
通过声明全局我的意思是,我在方法中使printwriter对象不在方法 – Waqas
因此,在一个静态初始化? – fge
