The byteValue() method returns the value of this Integer as a byte.Following is an example to implement the byteValue() method in Java −Examplepublic class Main { public static void main(String[] args) { Integer val = new Integer(10); byte res = val.byteValue(); System.out.println("Value = " + res); } }OutputValue = 10Let us see another example −Exampleimport java.util.*; public class Main { public static void main(String[] args) { Byte b = new Byte("10"); byte res = b.byteValue(); System.out.println("Byte = " + b ); System.out.println("Primitive byte = "+ res); } }OutputByte = 80 Primitive byte = 80
The java.lang.Integer.bitCount() method returns the number of one-bits in the two's complement binary representation of the specified int value.At first, set an int value −int val = 210;Now, find the number of one-bits −Integer.bitCount(val)Following is an example to implement the bitCount() method in Java −Examplepublic class Main { public static void main(String[] args) { int val = 210; System.out.println("Number = " + val); System.out.println("Binary = " + Integer.toBinaryString(val)); // returns the number of one-bits System.out.println("Number of one bits = " + Integer.bitCount(val)); } }OutputNumber = 210 Binary = 11010010 Number of one bits = 4
At first sort the array −int intArr[] = {55, 20, 10, 60, 12, 90, 59}; // sorting array Arrays.sort(intArr);Now, set the value to be searched in an int variable −int searchVal = 12;Check for the presence of a value in an array −int retVal = Arrays.binarySearch(intArr, searchVal); boolean res = retVal > 0 ? true : false;Following is an example to check if a value is present in an array −Exampleimport java.util.Arrays; public class Main { public static void main(String[] args) { // initializing unsorted int array int intArr[] = {55, 20, 10, ...

Let’s say the string is −String str = "Malyalam";Let’s say the prefixes are in an array −String[] prefixArr = { "Ga", "Ma", "yalam" };Now, to check whether the string starts with any of the abive prefix, use the startsWith() −if (Stream.of(prefixArr) .anyMatch(str::startsWith)) System.out.println("TRUE"); else System.out.println("FALSE");Following is an example to check is a string starts with any of the given prefixes −Exampleimport java.util.stream.Stream; class Main { public static void main(String[] args) { String str = "Malyalam"; String[] prefixArr = { "Ga", "Ma", "yalam" }; if (Stream.of(prefixArr) ...
