Example

The following example shows the usage of math.BigDecimal.multiply() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create 3 BigDecimal objects
      BigDecimal bg1, bg2, bg3;

      MathContext mc = new MathContext(4); // 4 precision

      bg1 = new BigDecimal("2.310");
      bg2 = new BigDecimal("4.620");

      // multiply bg1 with bg2 using mc
      bg3 = bg1.multiply(bg2, mc);

      String str = "Multiplication Result is " +bg3;

      // print bg3 value
      System.out.println( str );
   }
}

Let us compile and run the above program, this will produce the following result −

Multiplication Result is 10.67
