Convert string into float class object using Float.valueOf() method.Ĭonverting String into Float Object using new Float(String).floatValue()Īnother alternative approach is to create an instance of Float class and then call floatValue() method of Float class. Program code 2: // Java Program to demonstrate the conversion of String into Float class object. Let’s take a very simple example program to convert String to float class object in Java. The valueOf() method throws an exception named NumberFormatException if the string cannot be parsed as a float. This method converts a string str containing some float number into a Float class object and returns that object holding the value of the specified string. The general signature of this method is as below: public static Float valueOf(String str) To convert a string to a float numeric value, we normally use Float.valueOf() method of Java Float class. Java String to Float Conversion using Float.valueOf() Convert string into float using Float.parseFloat() method. Program code 1: // Java Program to demonstrate the conversion of String into primitive float Let’s take a simple example program to convert a string to a float. The parseFloat() method throws an exception named NumberFormatException if the string does not contain a parsable float. This method accepts a string containing the float representation to be parsed. The general signature of parseFloat() method is as below: public static float parseFloat(String s) We can call it simply using its class name. So, we do not need to create an object of class to call it. The parseFloat() of Float class is the static utility method. To convert string to a float, we use Float.parseFloat() method from the Float class. Converting using new Float(String).floatValue()Ĭonvert String to Float in Java using Float.parseFloat().There are the following ways to convert a string to a primitive type float in Java. If entered data is a float number in string form, we need to convert the string to a float to perform mathematical operations on it. For example, whenever we gain data from JTextField or JComboBox, we receive entered data as a string.
