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

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, ...

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); ...

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 String, firstly let us declare and initialize a byte array.// byte array byte[] arr = new byte[] {78, 79, 33};Now take a String and include the array in it.String str = new String(arr);Let us see the complete example to convert byte array to String.Example Live Demopublic class Demo { public static void main(String args[]) { // byte array byte[] arr = new byte[] {78, 79, 33}; String str = new String(arr); // string System.out.println("String = "+str); } }OutputString = NO!

To convert hex string to byte array, you need to first get the length of the given string and include it while creating a new byte array.byte[] val = new byte[str.length() / 2];Now, take a for loop until the length of the byte array.for (int i = 0; i < val.length; i++) { int index = i * 2; int j = Integer.parseInt(str.substring(index, index + 2), 16); val[i] = (byte) j; }Let us see the complete example.Example Live Demopublic class Demo { public static void main(String args[]) { String str = "p"; ...

To check whether the entered value is a digit or not in Java, use the Character.isDigit() method.We have a character to be checked.char val = '5';Now let us use the Character.isDigit() method.if (Character.isDigit(val)) { System.out.println("Character is a digit!"); } else { System.out.println("Character is not a digit!"); }Let us see the complete example now to check for Uppercase in Java.Example Live Demopublic class Demo { public static void main(String []args) { System.out.println("Checking for digit..."); char val = '5'; System.out.println("Value: "+val); if (Character.isDigit(val)) { ...
