swing - Show a message in a message window in Java -


i want show message window displaying string value, don't know how write it. have code:

for (bufferedimage bimage : lineimage1) {     int trafficsection[] = analysis.colorshare(screencapturing.getmaptrafficonly(), bimage);     string trafficstring = trafficsection[0] + " - " + trafficsection[1] + " - " + trafficsection[2] + " - " + trafficsection[3];      joptionpane.showmessagedialog(this, trafficstring, joptionpane.information_message); }

but doesn't work. can me please how write code message window?

thanks

here error:

java: no suitable method found showmessagedialog(<anonymous cege.controller.screencapturecontroller.screencapturelistener>,java.lang.string,java.lang.string,int)     method javax.swing.joptionpane.showmessagedialog(java.awt.component,java.lang.object,java.lang.string,int,javax.swing.icon) not applicable       (actual , formal argument lists differ in length)     method javax.swing.joptionpane.showmessagedialog(java.awt.component,java.lang.object,java.lang.string,int) not applicable       (actual argument <anonymous cege.controller.screencapturecontroller.screencapturelistener> cannot converted java.awt.component method invocation conversion)     method javax.swing.joptionpane.showmessagedialog(java.awt.component,java.lang.object) not applicable       (actual , formal argument lists differ in length)

i solved it. put name of class before this.

joptionpane.showmessagedialog(null, "write msg here", "title msg", joptionpane.warning_message);

this warning message. if want other, change warning_message type (might take more or less params). http://docs.oracle.com/javase/7/docs/api/javax/swing/joptionpane.html

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
