如何使用函数来完成下表？

您使用打印f进行格式化是错误的。另外，不需要导入扫描仪。度是整数，但是您提供了f而不是d并且还提供了精度4.弧度是两倍。但您提供的d是错误的，我已更正，请检查以下代码。
public class St_Johns_University { public static void main(String[] args) { System.out.printf("%-10s%-10s%-10s%-10s%-10s\n", "Radians", "Tangent", "Sine", "Cosine", "Degrees");
int degrees = 60; double radians = Math.toRadians(degrees); System.out.printf("%-10f%-10.4f%-10.4f%-10.4f%-10d\n", radians, Math.tan(radians), Math.sin(radians), Math.cos(radians), degrees); degrees = 80; radians = Math.toRadians(degrees); System.out.printf("%-10f%-10.4f%-10.4f%-10.4f%-10d\n", radians, Math.tan(radians), Math.sin(radians), Math.cos(radians), degrees); degrees = 100; radians = Math.toRadians(degrees); System.out.printf("%-10f%-10.4f%-10.4f%-10.4f%-10d\n", radians, Math.tan(radians), Math.sin(radians), Math.cos(radians), degrees); degrees = 130; radians = Math.toRadians(degrees); System.out.printf("%-10f%-10.4f%-10.4f%-10.4f%-10d\n", radians, Math.tan(radians), Math.sin(radians), Math.cos(radians), degrees); degrees = 160; radians = Math.toRadians(degrees); System.out.printf("%-10f%-10.4f%-10.4f%-10.4f%-10d\n", radians, Math.tan(radians), Math.sin(radians), Math.cos(radians), degrees); }}
