对不起，如果这是显而易见的，我对Java没有经验。我有2个方法，一个创建一个BufferedReader，一个处理它。但是，处理方法无法访问BufferedReader，即使它处于公共方法。难道我做错了什么？缓冲阅读器无法通过其他方法访问
package textfiles;
import java.io.IOException;
import java.io.FileReader;
import java.io.BufferedReader;
public class ReadFile {
private String path;
public ReadFile(String filePath) {
path = filePath;
}
public void Open() throws IOException {
FileReader read = new FileReader(path);
BufferedReader buff = new BufferedReader(read);
}
public String[] OpenFile() throws IOException {
int numberOfLines = readLines();
String[] textData = new String[numberOfLines];
int i;
for (i=0; i < numberOfLines; i++) {
textData[i] = buff.readLine();
}
buff.close();
return textData;
}
int readLines() throws IOException {
FileReader linedFile = new FileReader(path);
BufferedReader findLines = new BufferedReader(linedFile);
String lines;
int noLines = 0;
while ((lines = findLines.readLine()) != null) {
noLines++;
}
findLines.close();
return noLines;
}
}
