Not directly. A String is an object, and a double is a primitive data type. To do the conversion you must first convert the String to a Double object (note the capital D in double), then convert that object to a double data type (lowercase d in double). Double is an object, double is a primitive data type. Here's a class that will convert a String to a double:
public class StringToDouble{
public static void main (String[] arguments) {
String s = "100.00";
double d = Double.valueOf(s.trim()).doubleValue();
System.out.println("double d = " + d);
}
}

What is type casting and what is the danger of casting from one type to another?
Type casting means that you explicitly convert from one type to another. Consider this example:int x;long y = 10;x = y;The compiler will protest, because of a possible overflow. Now, if you are confident - from a knowledge of the computer program you wrote - that there will be no overflow, you can explicitly:x = (int) y;You are telling the compiler that you know what you are doing. The danger, of course, is that you may be wrong, and there may still be an overflow.The situation is similar if you convert from double to float, or from double or float, to integer. In all of these cases, there is a loss of precision.

What are the differences between a double bass and an electric double bass?
The main difference between a double bass and an electric double bass is the way they produce sound. A double bass is an acoustic instrument that produces sound through the vibration of its strings and resonance of its wooden body. An electric double bass, on the other hand, uses electronic pickups to convert the vibrations of the strings into electrical signals, which are then amplified through speakers. This allows the electric double bass to produce a louder sound and be easily heard in amplified settings, such as concerts or recordings.
