如何从定义具有相同名称public class SimpleDBSearch {
public void sdbSearch(Scanner searchWord) throws IOException{
//Prompt user for input
System.out.println("Please input the word you wish to find:");
//Init string var containing user input
String wordInput = searchWord.next();
//Specify file to search
File file = new File("C:/Users/Joshua/Desktop/jOutFiles/TestFile.txt");
//Init Scanner containing specified file
Scanner fileScanner = new Scanner(file);
//Loops through every line looking for lines containing previously specified string.
while(fileScanner.hasNextLine()){
String line = fileScanner.nextLine();
if(line.contains(wordInput)){ //If desired string is found, print line containing it to console
System.out.println("I found the word you're looking for here: " + line);
}else{ //If desired string not found, prompt user for new string. I want this to occur only once, not per every line-check
System.out.println("Please input a new word");
}
}
}
的成员函数的类中调用非成员函数listen()（包含自sys/socket.h）？
listen()答案 0 :(得分：7)
使用范围解析运算符::。
void Socket::listen(int port){
//...
::listen(sock_fd, 10);
^^
}
范围解析运算符::用于标识和消除不同范围中使用的标识符的歧义。
