如何在以下程序中读入整数?它不起作用。它目前无法编译。
/**
* Main class of the Java program.
*
*/
import java.util.Scanner;
//...
class Scanner{
Scanner in = new Scanner(System.in);
int num = in.nextInt();
}
public class Main {
public static void main(String[] args) {
// we print a heading and make it bigger using HTML formatting
System.out.println("<h4>-- Binaere Suche --</h4>");
int anzahl = 0; int zahl;
}
}
答案 0 :(得分:0)
import java.util.Scanner;
// This will print what you want but will not make it look bigger as it
// will get printed in console
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int num = in.nextInt();
// we print a heading and make it bigger using HTML formatting
System.out.println("<h4>--"+num+" --</h4>");
}
}
