Explanation:

In java you can use pareDouble(string str) to convert the string into double.

for example if you have string like this.

string str  =

then you can use

double mydouble = Double.parseDouble(str);

print(mydouble); //it will print out 16.45

but if the string would not be able to be parsed into double then you will get an error.
