In order to get the array upperbound of a multidimensional array, we use the length() method. For a 2D array, the length() method returns the number of rows. We can access the number of columns using the array_name[0].length method.Let us see a program to get the array upperbound in Java Multidimensional arraysExample Live Demopublic class Example { public static void main(String args[]) { String[][] str = new String[5][10]; System.out.println("1st dimension : " + str.length); // displays the number of rows System.out.println("2nd dimension : " + str[0].length); // displays the number of columns } }Output1st dimension : 5 2nd dimension : 10
The reverse() function of the TypedArray object reverses the contents of a typed array.SyntaxIts Syntax is as followstypedArray.reverse()Example Live Demo JavaScript Array every Method var typedArray = new Int32Array([11, 5, 13, 4, 15, 3, 17, 2, 19, 8 ]); document.write("Contents of the typed array: "+typedArray); document.write(""); var result = typedArray.reverse(Math.sqrt); document.write("Contents of the reversed array: "+result); OutputContents of the typed array: 11,5,13,4,15,3,17,2,19,8 Contents of the reversed array: 8,19,2,17,3,15,4,13,5,11
The BYTES_PER_ELEMENT property of the Typed Array represents the number of bytes in each element in it.SyntaxIts Syntax is as followsFloat32Array.BYTES_PER_ELEMENT;Example Live Demo JavaScript Example var sizeOfFloat64Array = Float32Array.BYTES_PER_ELEMENT; document.write("Size of the float 32 array: "+sizeOfFloat64Array); document.write(""); var sizeOfInt16Array = Int16Array.BYTES_PER_ELEMENT; document.write("Size of the int 16 array: "+sizeOfInt16Array); OutputSize of the float 32 array: 4 Size of the int 16 array: 2
Use the CSS user-select property to set whether the text of the element can be selected or not with CSS:ExampleLive Demo div { user-select: none; } This is demo heading This is demo text. You won't be able to select it.
There is no whoami function in MySQL. The whoami can be used to know the current user in UNIX. Use user() or current_user() function from MySQL for the same purpose.The following is the output.+-----------+ | version() | +-----------+ | 8.0.12 | +-----------+ 1 row in set (0.00 sec)Case 1 −Using CURRENT_USER() function.The query to know the current user is as follows.mysql> select current_user();The following is the output.+----------------+ | current_user() | +----------------+ | root@% | +----------------+ 1 row in set (0.00 sec)Case 2 − Using USER() function.The query is as follows −mysql> select user();The following is ...

The name property of the TypedArray object represents the name of the typed array in string (format)i.e. one of Int8Array, Uint8Array, Uint8ClampedArray, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array.SyntaxIts Syntax is as followsFloat32Array.name;Example Live Demo JavaScript Example var nameOfarray1 = Float32Array.name; document.write("name of array1: "+nameOfarray1); document.write(""); var nameOfarray2 = Int16Array.name; document.write("name of array2: "+nameOfarray2); Outputname of array1: Float32Array name of array2: Int16Array
To implement animation on font property with CSS, you can try to run the following code:ExampleLive Demo p { border: 2px solid black; width: 400px; height: 100px; animation: myanim 5s infinite; } @keyframes myanim { 70% { font: 35px arial, sans-serif; } } This is demo text
The buffer property of the TypedArray represents the ArrayBuffer of the current TypedArray.SyntaxIts Syntax is as followsobj.buffer;Example Live Demo JavaScript Example var buffer = new ArrayBuffer(156); var float32 = new Float32Array(buffer); document.write(float32.buffer.byteLength); Output156
The byteLength property of the TypedArray object represents the length of its(in bytes)TypedArray.SyntaxIts Syntax is as followstypedArray.byteLength();Example Live Demo JavaScript Example var buffer = new ArrayBuffer(156); var float32 = new Float32Array(buffer); document.write(float32.byteLength); Output156
The byteOffset property of the TypedArray represents the offset of the current object.SyntaxIts Syntax is as followstypedArray.byteOffset();Example Live Demo JavaScript Example var buffer = new ArrayBuffer(156); var float32 = new Float32Array(buffer); document.write(float32.byteOffset); Output0
