Here, we are using the valueOf() method of the String class to get a string from a float value. Syntax: public static float parseFloat (String s) throws NumberFormatException Parameters: s - This is the string to be parsed. This method executes same as valueOf () method of Float class. Let's take an example to convert float to a string. Formatter (Java Platform SE 8 ) Class Formatter All Implemented Interfaces: Closeable, Flushable, AutoCloseable public final class Formatter extends Object implements Closeable, Flushable An interpreter for printf-style format strings. Method 1 : Java Program to Convert String to float Using parseFloat () method. The parseFloat () method of Java Float class returns a new float value that is initialized to the value corresponding to defined String. Here, we are going to see all these conversions with the help of several examples. NumberFormatException - If the string passed does not hold a parsable float. Throws: The parseFloat() method throws: NullPointerException - If the string passed is null. The valueOf() method belongs to String that returns a string of the specified value and The toString() method of Float class returns a string of the floating-point value. Return Value: The parseFloat() method returns the float value corresponding to the parameter passed. 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. Float is a datatype that holds floating-point values whereas String is a sequence of characters and a class in Java. Use parseFloat(String) to convert a string to a float primitive, or use valueOf(String) to convert a string. Some of them are using Float.parseFloat(), Float.valueOf(), new Float(). It is rarely appropriate to use this constructor. In this post, we are going to convert float type to string in Java. You can typecast or convert a string to float in Java in many ways. Using Float.valueOf(): This is a built-in static method of Float class that accepts a given string which is to be converted into float and returns a float value.
