Java Program to convert String to Double

Java 8Object Oriented ProgrammingProgramming

To convert String to Double in Java, you can use the following three examples. Two of them are using in-built methods parseDouble() and valueOf(). However, one of the method isn’t using a method.

Let us work through them one by one.

The following is an example to convert String to Double without using a method −

Example

 Live Demo

public class Demo {
    public static void main(String args[]) {
       Double val = new Double("88.77");
       System.out.println(val);
    }
}

Output

88.77

The following is another example to convert String to Double. Here, we will use parseDouble() method −

Example

 Live Demo

public class Demo {
    public static void main(String args[]) {
       double val = Double.parseDouble("11.89");
       System.out.println(val);
    }
}

Output

11.89

Let us see an example to convert String to Double using valueOf() method −

Example

 Live Demo

public class Demo {
    public static void main(String args[]) {
       Double val = Double.valueOf("299.9");
       System.out.println(val);
    }
}

Output

299.9
