Conversion from double to boolean:

In this tutorial we will learn how to convert a double type value to boolean type value.

Description:

This program will take a double value from console and provide the conversion to boolean type. The line double mydouble = Double.parseDouble(buffreader.readLine()); reads the double type value from console. The line boolean myboolean = (mydouble!=0); checks the condition if mydouble value is not equal to zero the mybool value will be true otherwise false.

Code:

import java.io.*;

class doubletoboolean{
public static void main(String[] args) {
try {
// Reads the value from console
BufferedReader buffreader = new BufferedReader(new InputStreamReader(System.in));
System.out.println("---Data Conversion from double type to boolean type---");
System.out.println("Enter double type value: ");
// Read double type data
double mydouble = Double.parseDouble(buffreader.readLine());
// Convert double type data to boolean type
boolean myboolean = (mydouble!=0);
System.out.println("Converted value from double type to boolean type is : " + myboolean);
} 
catch (Exception e) {
System.out.println(" Error " + e);	
}
}
}
