The previousDouble() method of java.text.ChoiceFormat class is used to get the double value just lesser than the passed double value.
Syntax: 

public static final double previousDouble(double d)

Parameter: This method accepts double value d as a parameter for which the previous double value is returned.
Return Value: This method returns an double value just lesser than the passed double value.
Below are the examples to illustrate the previousDouble() method:
Example 1:  

Java




// Java program to demonstrate
// previousDouble() method
 
import java.text.*;
import java.util.*;
import java.io.*;
 
public class GFG {
    public static void main(String[] argv)
    {
        // getting double value just
        // lesser than the passed value
        // using previousDouble() method
        double value
            = ChoiceFormat.previousDouble(22);
 
        // display the result
        System.out.print("Lesser double value: "
                         + value);
    }
}


Output: 

Lesser double value: 21.999999999999996

 

Example 2: 

Java




// Java program to demonstrate
// previousDouble() method
 
import java.text.*;
import java.util.*;
import java.io.*;
 
public class GFG {
    public static void main(String[] argv)
    {
        // calling getValue() method
        getValue(1.23d);
        getValue(10d);
        getValue(-12d);
        getValue(1.2f);
        getValue(50);
    }
 
    // defining getValue() method
    public static void getValue(double doub)
    {
 
        // getting double value just
        // lesser than the passed value
        // using previousDouble() method
        double value
            = ChoiceFormat.previousDouble(doub);
 
        // display the result
        System.out.println("Just lesser than "
                           + doub + ": "
                           + value);
    }
}


Output: 

Just lesser than 1.23: 1.2299999999999998
Just lesser than 10.0: 9.999999999999998
Just lesser than -12.0: -12.000000000000002
Just lesser than 1.2000000476837158: 1.2000000476837156
Just lesser than 50.0: 49.99999999999999
