Here is our string.String str = "Asia is a continent!";Now let us use a byte array and the getBytes() method to fulfill our purpose.byte[] byteVal = str.getBytes();Now, if we will get the length of the array, it would return the length as shown in the complete example below −Example Live Demopublic class Demo { public static void main(String args[]) { String str = "Asia is a continent!"; System.out.println(str); // converted to byte array byte[] byteVal = str.getBytes(); // getting the length System.out.println(byteVal.length); } }OutputAsia is a continent! 20
To convert Byte to numeric primitive data types, use the following methods −byteValue() shortValue() intValue() longValue() floatValue()Firstly, let us declare a Byte.Byte byteVal = new Byte("35");Now, let us see how to convert it to long type, for a simple example.long longVal = byteVal.longValue(); System.out.println(longVal);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[]) { // byte Byte byteVal = new Byte("35"); byte b = byteVal.byteValue(); System.out.println(b); ...

You can select the first and last data row using MIN() and MAX(). The syntax is as follows −SELECT * FROM yourTableName WHERE yourColumnName = (SELECT MIN(yourColumnName) FROM yourTableName) UNION SELECT * FROM yourTableName WHERE yourColumnName = (SELECT MAX(yourColumnName) FROM yourTableName) ;To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table FirstAndLastDataDemo -> ( -> EmployeeId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> EmployeeName varchar(20), -> EmployeeAge int -> ); Query OK, 0 rows affected (0.59 sec)ExampleInsert some records in the table using ...

To compare two Java short arrays, use the Arrays.equals() method.Let us first declare and initialize some short arrays.short[] arr1 = new short[] { 20, 15, 35, 55, 69 }; short[] arr2 = new short[] { 20, 15, 35, 55, 69 }; short[] arr3 = new short[] { 22, 19, 30, 45, 78 };Now let us compare any two of the above arrays.Arrays.equals(arr1, arr2));In the same way, work it for other arrays and compare themExample Live Demoimport java.util.*; public class Demo { public static void main(String []args) { short[] arr1 = new short[] { 20, 15, 35, 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
A great many people now purchase laptops for their processing needs and need to settle on the choice between getting either a Solid State Drive (SSD) or Hard Disk Drive (HDD) as the storage component. So which of the two is the better decision, an SSD or HDD?There's no straightforward response to this question; every buyer has different necessities and we need to evaluate our choice in light of those requirements, your preferences and obviously the cost.Despite the fact that the cost of SSDs has been falling, the cost per gigabyte advantage is still firm with HDDs. However, in the ... Read More
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
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
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
In the present world, technology has got very advanced. Most of our daily tasks have been automated which has made us more reliable on electronic gadgets. Wireless Charging gives an advantageous, safe, and solid approach to charge and power a large number of electrical gadgets at home, in the work, and in industries.By removing the use of physical connectors and links, remote charging makes it efficient and brings cost and safety advantages over the conventional charging wire. From cell phones to hand-held mechanical gadgets and heavy duty gear applications, wireless power keeps them protected, constant and maintains the reliable exchange ... Read More
