Question

System.out.printf怎么用，为什么我打出来会报错

    System.out.printf("%-10s%-10s%-10s%-10s%-10s\n", "Degrees", "Radians", "Sine", "Cosine", "Tangent");
    int degrees = 30;
    double radians = Math.toRadians(degrees);
    System.out.printf("%-10d%-10.4f%-10.4f%-10.4f%-10.4\n", degrees,
      radians, Math.sin(radians), Math.cos(radians),
      Math.tan(radians));

    degrees = 60;
    radians = Math.toRadians(degrees);
    System.out.printf("%-10d%-10.4f%-10.4f%-10.4f%-10.4\n", degrees,
              radians, Math.sin(radians), Math.cos(radians),
              Math.tan(radians));
