In the code bellow the string is created but it doesn't aske for the user input(the bold part), It behaves fine with next() method.
import java.io.File;
import java.util.*;
public class VirtualKey {
public static void main(String[] args) {
Scanner Sc = new Scanner(System.in);
System.out.println("Welcome to the Calculator");
File folder = new File("C:\\Users\\Alifa\\OneDrive\\Documents\\Practice projects");
File[] listOfFiles = folder.listFiles();
int u = 1;
while(u==1) {
System.out.println("Please select the oppration you want to perform"+"\r\n"
+ "1.To see the list of all files." +"\r\n"
+ "2.To perform oppretaion on a specific file." +"\r\n"
+ "0.Exit." );
int c = Sc.nextInt();
if(c==1) {
Arrays.sort(listOfFiles);
for (int i = 0; i < listOfFiles.length; i++) {
System.out.println(listOfFiles[i].getName());
}}
else if(c==2) {
while(u==1) {
System.out.println("Please select the oppration you want to perform"+"\r\n"
+ "1.To add a file" +"\r\n"
+ "2.To Delete a file." +"\r\n"
+ "3.To search a specific file."+"\r\n"
+ "0.To go back to main context." );
int a = Sc.nextInt();
if(a==1) {
}
else if(a==2) {
}
else if(a==3) {
System.out.println("Please, give the file name that you want to find with right extention: ");
**String filename= Sc.nextLine();**
System.out.println(filename);
for (int i = 0; i < listOfFiles.length; i++) {
String str = listOfFiles[i].getName();
if (str.equals(filename)) {
System.out.println("Your file has been found.");
break;
}
else if (i==listOfFiles.length-1) {
System.out.println("Your file not found. Please, make sure you entered correct file name with the right extention.");
}
}
}
else if(a==0) {
break;
}
else {
System.out.println("Please select a valid option");
}
}}
else if(c==0) {
System.out.println("The program is closed.");
break;
}
else {
System.out.println("Please select a valid option");
}
}
}}
I have added a Screenshot of the out put, can some please help me fix this.enter image description here
