This method scans the next token of the input as a float. This method will throw InputMismatchException if the next token cannot be translated into a valid float value as described below. If the translation is successful, the scanner advances past the input that matched.
Syntax:Library: java.util.Scanner
public float nextFloat()
Example:import java.util.*;
public class ScannerDemo {
public static void main(String[] args) {
String s = "Hello World! 3 + 3.0 = 6.0 true ";
Float f = 1.2385f;
s = s + f;
// create a new scanner with the specified String Object
Scanner scanner = new Scanner(s);
// use US locale to be able to identify floats in the string
scanner.useLocale(Locale.US);
// find the next float token and print it
// loop for the whole scanner
while (scanner.hasNext()) {
scanner.next();
// if the next is a float, print found and the float
if (scanner.hasNextFloat()) {
System.out.println("Found :" + scanner.nextFloat());
}
}
// close the scanner
scanner.close();
}
}
Output
Found :3.0
Found :3.0
