To check for Integer overflow, we need to check the Integer.MAX_VALUE with the added integers result, Here, Integer.MAX_VALUE is the maximum value of an integer in Java.Let us see an example wherein integers are added and if the sum is more than the Integer.MAX_VALUE, then an exception is thrown.Example Live Demopublic ...

The Boolean literals have two values i.e. True and False.The following is an example to display Boolean Literals.Example Live Demopublic class Demo {    public static void main(String[] args) {       System.out.println("Boolean Literals");       boolean one = true;       System.out.println(one);       one = ...

The method returns the signum function of the specified int value. Let us now see the syntax.int signum(int i)Here is the parameter.i − This is the int valueThe return value is -1 if the specified value is negative, 0 if the specified value is zero and 1 if the specified ... Read More

To convert Boolean Primitive to Boolean object, use the valueOf() method in Java.Firstly, let us take a boolean primitive.boolean val = false;To convert it into an object, use the valueOf() method and set the argument as the boolean primitive.Boolean res = Boolean.valueOf(val);Let us see the complete example to learn how ... Read More

To create a Boolean object from Boolean value is quite easy. Create an object with Boolean and set the Boolean value “true” or “false”, which are the Boolean literals.Let us now see how “true” value is added.Boolean bool = new Boolean("true");In the same way, “False” value is added.Boolean bool = ...

To convert Boolean to String in Java, use the toString() method. For this, firstly, we have declared two booleans.boolean bool1 = false; boolean bool2 = true;Now, convert Boolean to String using the toString() method in Java as shown below −String str1 = new Boolean(bool1).toString(); String str2 = new Boolean(bool2).toString();Now, when ... Read More

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 ... Read More

Use the valueOf() method to convert string to byte. Firstly, let us take a string.String str = "65";Now, use the valueOf() method to convert string to byte.byte res = Byte.valueOf(str);Let us see the complete example.Example Live Demopublic class Demo {    public static void main(String[] args) {       String ...

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 ... Read More

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 ...
