The methods like String.format() and DecimalFormat.format() are used to alter the digits after decimal places and round off the values to their nearest ones. It uses this property to convert double to string.Įach method can be used for different purposes and places. +operator - The +operator in Java is used to concatenate strings.There is chance that this conversion can lose information about the overall magnitude of the BigInteger value. If the value return by this function is too big to fit into long value, then it will return only the low-order 64 bits. StringBuffer and StringBuilder - StringBuffer and StringBuilder are classes in Java to create a modifiable chain and sequences of characters using the append() method. The () converts this BigInteger to a long value.DecimalFormat.format() - DecimalFormat.format() is a method in package that converts double to string with specified number of digits after decimal.Let’s understand all four ways one by one with example programs. Convert using Long.parseLong () Convert using Long.valueOf () Using new Long (String).longValue () Using DecimalFormat. toString() - toString() is an inbuilt function in Java to convert given value to string. There are mainly four different ways to convert a string to wrapper Long class or primitive type long.String.format() - It is used in java to return formatted strings with the specified format and arguments.valueOf() - String.valueOf() is an inbuilt method of String class in Java that converts different parameters to strings.If we want to do it for other purposes, we can convert it using the following methods: Conclusionĭouble values automatically get converted to string at the time of printing. This method helps us in rounding decimals. The above code helps us in adjusting the number of digits after the decimal to two in the output string. The following code converts a double number to a string using the String.valueOf method. Parameters: object, float, char, double, int, float, long, char String output = String.valueOf(parameter). Since it is an inbuilt method, it is already present in the java directory. It works with parameters like object, float, char, double, int, long, and char. String.valueOf() is an inbuilt method of String class in Java which converts different parameters to string. Example 1: Converting from Double to String Using valueOf() Method in Java Let's have a closer look at each one of them. Each of them has different use and properties. There are different inbuilt functions to convert double to string lie valueOf(), toString(), DecimalFormat.format() and many others. Strings help us in storing a large number that other data types fail to store. The double data type can be converted to string in JAVA using inbuilt functions present in Java class libraries. To understand the concepts covered in the article you should have a basic knowledge of data types and strings. There are different methods to convert double numbers to strings in Java. Strings help us in storing larger numbers that do not fit in any data type like integer or double. The double data type can be converted to string in Java using inbuilt functions present in Java libraries.
