Java bigdecimal multiply method example


Example below demonstrates bigdecimal class multiply method example. Method returns a bigdecimal object value. Method multiply  this.object value with the value of the specified object. Scale of the result will be as per context settings.

In the example two bigdecimal objects are created and assigned integer as well double type values. 
Method throws NumberFormatException if it finds value other than integer & double.

Syntax for using the method : public BigDecimal multiply(BigDecimal multiplicand, MathContext mc)
BigDecimal objects with names x ,y & z;
y = x.multiply(y,mc);





import java.math.BigDecimal;
import java.math.MathContext;

public class Java_bigdecimal_multiply_example {
  public static void main(String args[]) {

    MathContext mc = 
      new MathContext(BigDecimal.ROUND_DOWN);

    Integer value_0 = new Integer(2),
    value_1 = new Integer(100);

    BigDecimal nick = new BigDecimal(value_0);
    BigDecimal charle = new BigDecimal(value_1);

    System.out.println("nick object value : " +
        "" + nick
        "\ncharle object value :" + charle);
    System.out.println("Method generated result : "
        + nick.multiply(charle, mc));

    nick = new BigDecimal(13);
    charle = new BigDecimal(13);

    System.out.println("\n" "nick object value " +
        ": " + nick
        "\ncharle object value :" + charle);
    System.out.println("Method generated result : " +
        "" + nick.multiply(charle));
