据提供的引用内容，这是一个C语言的代码示例，而不是Java。以下是Java的代码示例：

import java.util.Scanner;

public class TaxCalculator {
    public static void main(String[] args) {
        double salary, rate, tax = 0;
        Scanner input = new Scanner(System.in);
        salary = input.nextDouble();
        if (salary <= 1500) {
            rate = 0.03;
            tax = rate * salary;
        } else if (salary <= 4500) {
            rate = 0.10;
            tax = rate * (salary - 1500) + 45;
        } else if (salary <= 9000) {
            rate = 0.20;
            tax = rate * (salary - 4500) + 345;
        } else {
            rate = 0.25;
            tax = rate * (salary - 9000) + 1245;
        }
        System.out.printf("tax=%.2f", tax);
    }
}
