Every data type in Java has a minimum as well as maximum range, for example, for Integer.Minimum = -2147483648 Maximum = 2147483647Let’s say for Integer, if the value extends the maximum range display above, it leads to Overflow. However, if the value is less than the minimum range displayed above, it leads to Underflow.The following program displays the limits on datatypes in Java.Example Live Demopublic class Demo {    public static void main(String[] args) {       System.out.println("Limits of primitive DataTypes");       System.out.println("Byte Datatype values...");       System.out.println("Min = " + Byte.MIN_VALUE);       System.out.println("Max = ...

The Integer.numberOfTrailingZeros() method returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of the specified int value.We have the following decimal as an example.int dec = 199;Calculated binary using Integer.toBinaryString() as shown below −Integer.toBinaryString(dec);Now let us see the implementation of Integer.numberOfTrailingZeros() method.Example Live Demopublic class Demo {    public static void main(String []args) {       int dec = 199;       System.out.println("Binary = " + Integer.toBinaryString(dec));       System.out.println("Count of one bits = " + Integer.bitCount(dec));       System.out.println("Number of trailing zeros : " + Integer.numberOfTrailingZeros(dec));    } ...

This Integer.numberOfLeadingZeros() method in Java returns the number of zero bits preceding the highest-order ("leftmost") one-bit in the two's complement binary representation of the specified int value.We have the following decimal as an example.int dec = 294;Calculated binary using Integer.toBinaryString() as shown below −Integer.toBinaryString(dec);Now let us see the implementation of Integer.numberOfLeadingZeros() method.Example Live Demopublic class Demo {    public static void main(String []args) {       int dec = 294;       System.out.println("Decimal = " + dec);       System.out.println("Binary = " + Integer.toBinaryString(dec));       System.out.println("Count of one bits = " + Integer.bitCount(dec));       ...

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
