The StringBuffer object represents a String object that we can change and treat as an array with a sequence of characters. StringBuffer is a class that concatenates multiple values into a single string.
("String representation is: " + str) Ĭonvert Double to String in Java using StringBuffer
#CONVERT STRING TO DOUBLE CODE#
Program code 5: // Java Program to demonstrate the conversion of double into string using DecimalFormat.ĭecimalFormat numberFormat = new DecimalFormat("#,#") Here’s an example program using DecimalFormat. We can use it to format a number to a string representation using a certain pattern. It provides a lot of features designed to parse and format numbers. Program code 4: // Java Program to demonstrate the conversion of double value into string using format() method.Ĭonverting Double to String using DecimalFormatĭecimalFormat is a concrete subclass of NumberFormat class that formats a number to a string representation. Let’s create a Java program to convert a primitive double to string in Java using format() method of String class. The general syntax for this method is as below: public static String format(String format, Object. The purpose of this method is to format a string. This is a new alternative way for converting a Double class object to a string object. The String.format() method of String class formats given arguments into String. ("String representation: " +str) Ĭonvert Double to String using String.format()
Program code 3: // Java Program to demonstrate the conversion of double into string using new Double(double).toString(). Look at the below example program based on it. We can also convert double to string by creating Double class object and then invoking its toString() method. Call toString() method of Double class for converting double to string.Ĭonverting Double to String using new Double(double).toString() Program code 2: // Java Program to demonstrate the conversion of double into string using Double.toString(). Let’s create a simple Java program to convert a double value to string in Java using Double.toString() method. The general signature of this method is as below: public static String toString(double d) It returns a string object representing the specified double value. The toString() method of Double class is a static utility method. The Double wrapper class in Java also provides a toString() method that converts double numeric value to String. (str + 200) // 789.999200 because + is string concatenation operator.Ĭonverting Double to String in Java using Double.toString(double)
#CONVERT STRING TO DOUBLE PLUS#
(num + 200) // 789.999 because + is binary plus operator. Call valueOf() method of String class for converting double to string. Program code 1: // Java Program to demonstrate the conversion of double into string using String.valueOf(). Let’s create a simple program to convert a primitive double to string value in Java. This method accepts an integer value that needs to be converted and returns the string representation of the double value. The general signature of valueOf() method is as below: public static String valueOf(double d) We can simply call by using its class name. Therefore, we do not need to create an object to calling this method. It is a static utility method of the String class.
The method String.valueOf() converts double to string. To convert primitive type double to string in Java, we use valueOf() method of the String class. Converting Double to String in Java using String.valueOf() Let’s understand all the above ways one by one with example programs.
