How Y

this question has answer here: is java “pass-by-reference” or “pass-by-value”? 73 answers are arrays passed value or passed reference in java? [duplicate] 7 answers suppose have following code: public static void main(string[] args) { int x = 5; int [] array = new int[10]; swtich (x, array); system.out.println("x = " + x); system.out.println("y[0] = " + y[0]); } public static void switch(int number , int[] array){ number = 10; array[0] = 150; } why program prints 5 (doesn't change value) , prints number ordered in array[0] 150? thanks.

as far know, interfaces cannot instantiated directly. however, whenever compile following code: interface {}; public class test { public static void main(string[] args){ a = new a() {}; system.out.println(a); it outputs tostring() of object of class test: test$16d06d69c and when change a = new a() {}; to a = new a(); it doesn't compile. why happening? interface being instantiated, or else happening behind scenes? you defining new anonymous inline class implements interface statement: a = new a() {}; and in same statement constructing new instance of new anonymous class definition. so no not instantiating interface.

i wrote script lets me delete iframes page pressing button: window.addeventlistener('load', function() { var addbutton = document.createelement("button"); addbutton.innerhtml = "delete iframes"; addbutton.onclick = removealliframes; document.body.appendchild(addbutton); }); function removealliframes() { var iframes = document.getelementsbytagname("iframe"); (var frame of iframes) { frame.parentnode.removechild(frame); } } while works, wondering if possible listen iframe insertions , delete them appear on page. there sort of window.listentoelementinsertionbytag() method can automate this? otherwise use setinterval() , execute removealliframes() method on interval.

i want create endpoint has pathparam automatically calls constructor of object injected, has constructor of string argument. spell out in code: here resource @get @path("/{apiversion}" + "/item") public response version(@pathparam("apiversion") apiversion apiversion) { return response.ok().build(); } i want string automatically used in call apiversion constructor. in apiversion class public apiversion(string apiversion) { this.versionstring = apiversion; } is possible access annotations? not have access resourceconfig . yes, possible, without annotations other @pathparam , example you've given should work as-is. see https://jersey.github.io/documentation/latest/jaxrs-resources.html#d0e2271 (emphasis mine) : in general java type of method parameter may: be primitive type; have constructor accepts single string argument; have static method named valueof or fromstring accepts single string argument...
