Java BigDecimal multiply() method

The multiply() method of java BigDecimal class is used to obtain a BigDecimal whose value is (this � multiplicand), and whose scale is (this.scale() + multiplicand.scale()) with rounding according to the context settings.

Syntax:

public BigDecimal multiply(BigDecimal multiplicand)
public BigDecimal multiply(BigDecimal multiplicand, MathContext mc)

Parameter:

multiplicand: value to be multiplied by this BigDecimal.

mc: the context to use.

Exception:

ArithmeticException- if the result is inexact but the rounding mode is UNNECESSARY, then it throws exception :

Returns:

It returns this*multiplicand, rounded as necessary.

Example 1

import java.math.BigDecimal;  
public class BigDecimalMultiplyExample1 
{
	public static void main(String[] args) 
	{
        // Creating BigDecimal objects
        BigDecimal bdValue_1, bdValue_2, multiplyresult;
        
        //Assigning value into BigDecimal objects 
        bdValue_1= new BigDecimal("34.203");
        bdValue_2= new BigDecimal("44.25");
 
        // it returns multiplication result as BigDecimal value
        multiplyresult = bdValue_1.multiply(bdValue_2);
 
        // Displaying result of multiplication
        System.out.println("Multiplication of "+bdValue_1+" and "+bdValue_2+"  is  =" + multiplyresult);
	}
}

Test it Now

Output:

Multiplication of 34.203 and 44.25  is  =1513.48275

Example 2

import java.math.BigDecimal;  
public class BigDecimalMultiplyExample2 
{
	public static void main(String[] args) {

        // Creating BigDecimal objects
        BigDecimal bdValue_1, bdValue_2, multiplyresult;
        
        //Assigning value into BigDecimal objects 
        bdValue_1= new BigDecimal("-67");
        bdValue_2= new BigDecimal("25");
 
        // it returns multiplication result as BigDecimal value
        multiplyresult = bdValue_1.multiply(bdValue_2);
 
        // Displaying result of multiplication
        System.out.println("Multiplication of "+bdValue_1+" and "+bdValue_2+"  is  = " + multiplyresult);
	}
}

Test it Now

Output:

Multiplication of -67 and 25  is  = -1675

Example 3

import java.math.BigDecimal;  
public class BigDecimalMultiplyExample3 
{
	public static void main(String[] args) 
	{
        // Creating BigDecimal objects
        BigDecimal bdValue_1, bdValue_2, multiplyresult;
        
        //Assigning value into BigDecimal objects 
        bdValue_1= new BigDecimal("-120");
        bdValue_2= new BigDecimal("-35");
 
        // it returns multiplication result as BigDecimal value
        multiplyresult = bdValue_1.multiply(bdValue_2);
 
        // Displaying result of multiplication
        System.out.println("Multiplication of "+bdValue_1+" and "+bdValue_2+"  is  = " + multiplyresult);
	}
}

Test it Now

Output:

Multiplication of -120 and -35  is  = 4200
