Java array is a collection of multiple values of the same data type. Now we will discuss different ways to convert a bytearray to string in python. by calling getDouble () method we can get double value of that byte array. Float is a datatype that holds floating-point values whereas String is a sequence of characters and a class in Java.. To convert Float to String there are several ways like the valueOf() method of String class or toString() method of Float class or a simple string literal that converts an expression to string. This example is a part of the Java Basic Examples and Java Type conversion Tutorial. In the next section, you'll find similar methods for byte array to String. So we can use floatToIntBits or floatToRawIntBits functions available in the Float class of Java. Attached picture shows which bytes aro for each varible and also shows what is correct values for kWh as also for m3. In the following example, we shall take an integer variable initialized to a hexadecimal representation of 4 bytes. Hex String - A Hex String is a combination of the digits 0-9 and characters A-F, just like how a binary string comprises only 0's and 1's.Eg: "245FC" is a hexadecimal string.
