Why the arr[1] value is changing when changing the value of arr1[1]? This is your first question, but keep it now after answering the second. and similarly why it is changing when ((int[])o)[1] = 1000; This is your second question. Answer is by seeing what is the initial value of o variable. Object o = … Read more
1) You need a semicolon and the end of your prototype: float xc(float frequency, float capacitance); 2) Variable declarations don’t have “()” float f; float c; 3) arguments are separated by commas: capreac = xc(f, c); 4) argument names should match variable names: float xc(float frequency, float capacitance); { float answer; answer = (1.0/(2.0*pi*capacitance*frequency)); … … Read more
You can send you HTML as a JSON object. Here a quick example. var elm = document.getElementById(‘yourElement’); var value = elm.innerHTML; var objToSend = JSON.stringify(value); // now send using ajax … 1 solved Sending HTML to backend
I’ll give you a ggplot2 answer. For this, you need to reshape your data, so there are separate x and y variables. Right now, your y values are split between two columns. Then we highlight the specific genes by only plotting points for a subset. library(ggplot2) library(dplyr) library(tidyr) gene_list <- c(‘C’, ‘F’, ‘G’, ‘I’) df_long … Read more
Here is an explanation: foreach (@a) { # loop on all elements of array @a if ( $_ =~ m/active/ ) { # if current element contains ‘active’ s/ *//g; # removes all spaces s/\r//; # remove carriage return my @v = split(/\-/); # split on dash $_cfg{$v[0]} = $v[1]; # populates the hash %_cfg … Read more

You could try this for a input-file called input: csplit -f tempfile input ‘/-/+1’ ‘{*}’; paste tempfile* With csplit we generate one file for each “column” in the desired output (tempfile01, tempfile02, …). Next, we merge these temporary files. With the given sample input, the output of the above command is: jim sally bill jerry … Read more
This is how I did it: It is in C# but I think it is easy to convert it to Java. I used tag to know if this radio button checked before or not. False => It is not checked True => It is checked radiobutton.Tag = false; radiobutton.Click += SingleChoiceQuestionAlternativeClick; Then: private void SingleChoiceQuestionAlternativeClick(object … Read more

Can we declare an interface class by making all the methods abstract using the keyword ‘abstract’ in a class in C++? [duplicate] solved Can we declare an interface class by making all the methods abstract using the keyword ‘abstract’ in a class in C++? [duplicate]
change $header to $headers, you’ve got $headers = “From: $from\r\n”; and using $header mail($to, $subject, $message,$headers); so whole code would look like <?php //change this to your email. $to = “[email protected]”; $from = “[email protected]”; $subject = “Hello! This is HTML email”; $message = “hello”; $headers = “From: $from\r\n”; $headers .= “Content-type: text/html\r\n”; mail($to, $subject, $message,$headers); … Read more
if(temp[i].equals(object[j])) // It shows arrayout of bound exception Don’t want personally to be “Captain Obvious”, but it’s a good idea to check an index vs the array length before trying to access array item by index. For example: if((object.length > j) && (temp[i].equals(object[j]))) And yes, use “Array.equals()” to compare arrays, as @Prateek proposed before. solved … Read more
Maybe this… get the maximum sum for each city and menu item name. Top returns 1 row not one row per group. you need to use the max aggregate to make this work the way you want. you can’t double aggregate max(sum(Quantity)) so you have to either use a sub select, or use a CTE … Read more
Java is the standard way of writing Android apps, but it’s not strictly necessary. For example, there’s also Xamarin.Android which lets you write Android apps in C# – although it will still fire up a Dalvik VM behind the scenes, as the Android “native” controls are in Java. Using Java is probably the simplest option. … Read more
ArrayList is a list implementation that’s backed by an Object[]. It supports random access and dynamic resizing. LinkedList is a list implementation that uses references to head and tail to navigate it. It has no random access capabilities, but it too supports dynamic resizing. Bear in mind that both support the get(int index) signature, but … Read more
