use java simply implement code


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 :
 Insert picture description here
This is what it looks like when you open it :
 Insert picture description here
Take the path :
 Insert picture description here
Run the program , Paste the path into the program






 Insert picture description here
give the result as follows !!!
 Insert picture description here
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 !!
