Jjava读取文件内容的函数
public static String readFile(String fileName) {
String output = "";
File file = new File(fileName);
if (file. exists()) {
if (file. isFile()) {
try {
BufferedReader input = new BufferedReader(new FileReader(
file));
StringBuffer buffer = new StringBuffer();
String text;
while ((text = input. readLine()) != null)
buffer. append(text + "\n");
output = buffer. toString();
} catch (IOException ioException) {
System. err. println("File Error!");
}
} else if (file. isDirectory()) {
String[] dir = file. list();
output += "Directory contents:\n";
for (int i = 0; i < dir. length; i++) {
output += dir + "\n";
}
}
} else {
System. err. println("Does not exist!");
}
return output;
}
public static void main(String args[]) {
Map ab = new HashMap();
String str = readFile("C:/AbCircuitInfo");
String[] temp=str. split("\\n");
for (int i = 0; i < temp. length; i++) {
ab. put(temp. substring(0, temp. indexOf(", ")), temp. substring(temp. indexOf(", ")+1, temp. length()));
