Question

java做了一个程序，FileReader()不能识别JButton读取的路径

JButton按钮读取的路径是C:\Users\wan\Documents\sample.conf，但是FileReader()必须要C://Users//wan//Documents//sample.conf

public class TestFile {

public static String readFile() throws Exception {

Testpanel r = new Testpanel();
String path2 = r.getPath2();

File file = new File(path2);

BufferedReader br = new BufferedReader(new FileReader(file));

}
if (e1.getSource() == btnSelect2) {

int intRetVal = fc2.showOpenDialog(this);
if (intRetVal == JFileChooser.APPROVE_OPTION) {
txtfile2.setText(fc2.getSelectedFile().getPath());
}

Answer 1

源代码中路径应该是: C:\\Users\\wan\\Documents\\sample.conf 或者是

C:/Users/wan/Documents/sample.conf

path = fc2.getSelectedFile().getPath()应该已经在内部正确存储了路径，new FileReader(path)可以直接用
