import java.util.Scanner;

public class Guess
{
public static void main(String[] args)
{
Scanner scanner = new Scanner (System.in);
int number = (int) (Math.random() * 10);
int guess;

do
{
System.out.printf("GUESS A NUMBER:");
guess = scanner.nextInt();
}
while(guess != number);

System.out.println("YOU ARE RIGHT!");

}
}
java.math.BigDecimal避免了浮点数运算时失去精度。

import java.math.BigDecimal;

public class DecimalDemo { public static void main(String[] args) { BigDecimal operand1 = new BigDecimal ("1.0"); BigDecimal operand2 = new BigDecimal ("0.8"); BigDecimal result = operand1.subtract(operand2);

System.out.println(result);

} }
