ArrayBuffer.slice() function in JavaScript
ArrayBuffer object in JavaScript represents a fixed-length binary data buffer.The slice() method of the this object returns a portion or, chunk from the array buffer (as a separate object). It accepts two integer arguments representing the start (inclusive) and end (exclusive) of the portion of the array to be returned.SyntaxIts syntax is as followsarrayBuffer.slice(start, end);ExampleTry the following example. JavaScript Example var arrayBuffer = new ArrayBuffer(16); var int32View = new Int32Array(arrayBuffer); int32View[1] = 102; var sliced = new Int32Array(arrayBuffer.slice(4,12)); document.write(" "+sliced); Output102,0

The max() function Returns the maximum value of an array.Syntaxmax(arr_values); or max(val1,val2,...);Parametersarr_values − The array with values.val1, val2 − The values to compare.ReturnThe max() function Returns the maximum value of an array.ExampleOutput89ExampleLet us see another example −Output89
Read MoreJava Program to implement NOT operation on BigInteger
The BigInteger.not() method returns a BigInteger whose value is (~this). This method returns a negative value if and only if this BigInteger is non-negative.The following is an example −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one, two, three; one = new BigInteger("6"); two = one.not(); System.out.println("Result (not operation): " +two); } }OutputResult (not operation): -7Let us see another example −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger bi1, bi2, bi3, bi4; ...

To perform Bubble Sort, try the below given code. In this each each pair of adjacent elements is compared and the elements are swapped if they are not in order.The following is an example.Examplepublic class Demo { public static void main(String []args) { String str[] = { "s", "k", "r", "v", "n"}; String temp; System.out.println("Sorted string..."); for (int j = 0; j < str.length; j++) { for (int i = j + 1; i < str.length; i++) { ...
