问题 JavaScript (browser): I want to find out how deep the stack is. Basically, I want to know how many lines would be printed if I would call console.trace() . But I don't want to call console.trace() (and then count lines in the console window), I just want to 'have' that number of lines in a variable which I can then store to get some kind of performance statistics. Here is an example. function StackTest(limit){ this.inc = -1; this.limit = limit; } StackTest.prototype.test = function(n){ /

问题 I have two entities defined as so: @Entity @Table(name = "shapes") public class Shape { @Id private int id; @Column(nullable = false) private String name; @OneToMany(mappedBy="shape", fetch = FetchType.EAGER) private List<ShapeElement> shapeElements; public int getId() { return id; } } And: @Entity @IdClass(ShapeElementPK.class) @Table(name = "shape_elements") public class ShapeElement { @Id @ManyToOne @JoinColumn(name = "shape_id") private Shape shape; @Id @Column(name = "x_delta") private

问题 I have a simple method I've written for a class homework assignment that uses recursion (yes, it must use recursion) to calculate the number of triangles in a fractal pattern: public static BigInteger triangleFract(int layer) { if(layer < 0) { throw new IllegalArgumentException("Input must be >= 0"); } else if(layer == 0) { return new BigInteger("0"); } else if (layer == 1) { return new BigInteger("1"); } else { return triangleFract(layer - 1) .multiply(new BigInteger("3")) .add(new
