hello , I'm Xiaohei , I learned recently java After the input and output flow of the heart has been itching , Always looking for something to do , So use java Code to achieve the following statistics code all lines of code , Take a look at how many lines I've played since I went to college .
Attach the implementation code first ！
package InOutStream;
import java.util.* ;
import java.io.* ;
class codeCount {
private static int count ; // Total number of Statistics
private static int countCPP ;//CPP
private static int countJAVA ;//java
private static int countPY ;//python
private String path ; // Path to the folder used to receive user input to save code
private int reading(String path) throws Exception {
// This function is used to count the number of lines in a code file
FileReader reader = new FileReader(path) ;
BufferedReader buffer = new BufferedReader(reader) ;
int count = 0 ;
while(buffer.readLine()!=null) {
count ++ ;
}
buffer.close() ;
reader.close() ;
return count ;
}
private void caculate(String nowpath) throws Exception{
// Counting function
File nowfile = new File(nowpath) ;
if (nowfile.isFile()) {
if (nowpath.endsWith(".cpp")) {
int sum = reading(nowpath) ;
countCPP += sum ;
count += sum ;
}
else if (nowpath.endsWith(".py")) {
int sum = reading(nowpath) ;
countPY += sum ;
count += sum ;
}
else if (nowpath.endsWith(".java")) {
int sum = reading(nowpath) ;
countJAVA += sum ;
count += sum ;
}
else {
System.out.println(nowpath.substring(nowpath.indexOf("."))+": This type of file does not belong to the code file or the statistical function of the code file is under development , Coming soon ！");
}
}
else {
// If this path represents a folder , The recursive operation is performed
String []filesset = nowfile.list() ;
for (String i:filesset ) {
String newpath = nowpath + nowfile.separator + i ;// Synthesis path
caculate(newpath) ;
}
}
}
public codeCount(String src) {
path = src ;
}
public static int getLinesCPP() {
return countCPP ;
}
public static int getLinesJAVA() {
return countJAVA ;
}
public static int getLinesPY() {
return countPY ;
}
public static int getLines() {
return count ;
}
public void caculator() throws Exception {
// External packaging
this.caculate(path) ;
}
public String toString() {
// rewrite toString Method
return " The statistics are as follows :\n" +
"cpp Row number ：\n"+countCPP +
"\njava Row number ：\n"+countJAVA +
"\npython Row number ：\n"+countPY ;
}
}
public class Count{
public static void main(String []args) throws Exception {
Scanner cin = new Scanner(System.in) ;
System.out.println(" Please enter the address ：");
String path = cin.next() ;
codeCount machine = new codeCount(path) ;
machine.caculator();
System.out.println(machine.toString());
cin.close();
}
}
example ：
I saved a folder on my desktop to save the code ：
This is what it looks like when you open it ：
Take the path ：
Run the program , Paste the path into the program
give the result as follows !!!
This is all code pulling ！！ If you have any other implementation methods or comments or suggestions , Welcome to bring it up in the comments section ！
ps: Because I only learned c、cpp、java、python. So the code only for these kinds of Statistics , You are welcome to modify the code to meet your needs ！！
Next I'll learn swing, At that time, we will try to generate the code into a graphical interface . Welcome to pay close attention to me ！！！
Thank you for reading ！！
