Write a Java Program to convert string variables to double
PROGRAM: Java Program to convert string variables to double
/*Java Program to convert string variables to double*/
1: Java Program to Convert string to double using parseDouble()
class Main {
public static void main(String[] args) {
// create string variables
String str1 = “23”;
String str2 = “456.6”;
// convert string to double
// using parseDouble()
double num1 = Double.parseDouble(str1);
double num2 = Double.parseDouble(str2);
// print double values
System.out.println(num1); // 23.0
System.out.println(num2); // 456.6
}
}
2: Java Program to Convert string to double using valueOf()
class Main {
public static void main(String[] args) {
// create string variables
String str1 = “6143”;
String str2 = “21312”;
// convert String to double
// using valueOf()
double num1 = Double.valueOf(str1);
double num2 = Double.valueOf(str2);
// print double values
System.out.println(num1); // 6143.0
System.out.println(num2); // 21312.0
}
}
3: Java Program to Convert a String containing comma to double
class Main {
public static void main(String[] args) {
// create string variables
String str = “614,33”;
// replace the , with .
str = str.replace(“,”, “.”);
// convert String to double
// using valueOf()
double value = Double.parseDouble(str);
// print double value
System.out.println(value); // 614.33
}
}
