To create an Integer object in Java is quite easy. Let us learn about the following two ways for this purpose. Before moving to the coding section, let's briefly discuss the Integer class. The Integer class is a wrapper class in Java, which can be used to encapsulate a primitive int value in an object. Using an Integer Constructor You can create an Integer object using the Integer constructor by passing a primitive int value. In Java, a constructor is a special method whose name is exactly the same as the class name. Example The following example creates an Integer ... Read More

Let’s say we have the following decimal number, which is binary 100100110.int dec = 294;To perform bit manipulation, let us count the number of 1 bits in it. We have used bitCount() method for this purpose.Integer.bitCount(dec);The following is an example to display bit manipulation in given Integer.Example Live Demopublic class Demo {    public static void main(String []args) {       // binary 100100110       int dec = 294;       System.out.println("Count of one bits = " + Integer.bitCount(dec));    } }OutputCount of one bits = 4

To convert byte primitive type to Byte object, use the Byte constructor.Here is our byte primitive type.byte b = 100;Now let us convert it to Byte object.Byte res = new Byte(b);Let us see the complete example.Example Live Demopublic class Demo {    public static void main(String[] args) {       byte b = 100;       Byte res = new Byte(b);       System.out.println(res);    } }Output100

Suppose you are given a String named "str". Now, your task is to write a Java program to convert the given string to Byte. String is a class in Java which stores sequence of characters within double quotes and Byte is a wrapper class of java.lang package which wraps value of byte datatype. Example Scenario: Input: String str = "65"; Output: res = 65 Using Byte.valueOf() Method The valueOf() method of Java Byte class is used to convert given string into its corresponding Byte object. It accepts a single numeric string as a parameter value and returns it as ... Read More

In this article, we will learn to sort a short array in Java using the Arrays.sort() method. Begin by declaring and initializing an unsorted short array, then sort it and display the sorted array. Arrays.sort() method : This method sorts the elements of array in ascending order which have specified range and specified order. Syntax public static void sort(Object[] a, int fromIndex, int toIndex) Steps to sort short array Following are the steps to sort short array in Java − Declare and initialize an unsorted short array. ...

To convert Short to numeric primitive data types, use the following methods −byteValue() shortValue() intValue() longValue() floatValue()Firstly, let us declare a Short.Short shortObj = new Short("40");Now, let us see how to convert it to long type, for a simple example.long val5 = shortObj.longValue(); System.out.println("Long: "+val5);In the same way, you can convert it to other primitive data types as shown in the complete example below.Example Live Demopublic class Demo {    public static void main(String []args) {       Short shortObj = new Short("40");       byte val1 = shortObj.byteValue();       System.out.println("Byte: "+val1);       int val2 ...

Use the parseShort() method to convert String to short primitive. It parses the string argument as a signed short.Firstly, we have set a string.String str = "99";Now, we have taken a short primitive and included the string value.short val = Short.parseShort(str);The following is an example to convert String to short primitive.Example Live Demopublic class Demo {    public static void main(String []args) {       String str = "99";       short val = Short.parseShort(str);       System.out.println(val);    } }Output99

Let us first create a short primitive type and assign a value.short val = 30;Now, create a Short object and set the above short type to it.Short myShort = new Short(val);The following is the complete example to convert short primitive type to Short object using Short constructor.Example Live Demopublic class Demo {    public static void main(String []args) {       short val = 30;       Short myShort = new Short(val);       System.out.println(myShort);    } }Output30

Using toString() method to convert Short to string. Firstly, let us take a short primitive datatype and initialize a short value.short myShort = 55;Now let us include this value to the following Short object.Short s = new Short(myShort);Convert the above given Short to string using the toString() method as shown in the complete example below.Example Live Demopublic class Demo {    public static void main(String []args) {       short myShort = 55;       Short s = new Short(myShort);       System.out.println("Short: "+s);       String myStr = s.toString();       System.out.println("String: "+myStr);    } }OutputShort: 55 String: 55

Use valueOf() method to convert a String in Java to Short.Let us take a string.The following is an example −String myStr = "5";Now take Short object and use the valueOf() method. The argument should be the string we declared above.The following is an example.Short myShort = Short.valueOf(myStr);Let us now see the entire example to learn how to convert a string in Java to Short.Example Live Demopublic class Demo {    public static void main(String []args) {       String myStr = "5";       System.out.println("String: "+myStr);       Short myShort = Short.valueOf(myStr);       System.out.println("Short: "+myShort);    } }OutputString: 5 Short: 5
