Converting a double type variable to a string is a common task in Java programming.
In this tutorial, we will discuss how to convert a double type variable to a string in Java using two methods.
Using the toString() Method
The toString() method is a built-in method in Java that is used to convert a value to a string.
To convert a double type variable to a string using the toString() method, follow these steps:
- Declare a double type variable and assign a value to it.
double myDouble = 3.14159265359;
- Call the toString() method on the double variable and store the result in a string variable.
String myString = Double.toString(myDouble);
- Print the string variable.
System.out.println(myString);
Using String.valueOf() Method
The String class also has a valueOf() method that is used to convert a value to a string.
To convert a double type variable to a string using the valueOf() method, follow these steps:
- Declare a double type variable and assign a value to it.
double myDouble = 3.14159265359;
- Call the valueOf() method on the String class and pass the double variable as an argument.
String myString = String.valueOf(myDouble);
- Print the string variable.
System.out.println(myString);
Conclusion
In this tutorial, we have discussed how to convert a double type variable to a string using two methods in Java.
The first method involves using the toString() method, while the second method involves using the valueOf() method.
These methods are useful when working with numerical data in Java programming.
