Java bigdecimal subtract

     

Example below demonstrates working of bigdecimal class subtract method. Method returns bigdecimal object values. This bigdecimal class method subtracts the object value( in which the method is invoked) by the value of object specified. 

In shortly, method subtracts the specified object value from this.object value. 

Scale of the result is equivalent to the output of bigdecimal class max method. At the  left operand position of the max method,  scale of this.object value is located & at right operand, scale of the specified object value is located.

Syntatically its look like max (scale of this.object value,  scale of the value of specified object).

Method generates NumberFormatException, if it finds the bigdecimal value other than integers and double types values. 

Syntax for using the method: public BigDecimal subtract(BigDecimal subtrahend) 
Suppose three bigdecimal objects x, y & z then
z = x.subtract(y);
System.out.println(z); 

Java_bigdecimal_subtract.java

import java.math.BigDecimal;

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

  double valueD = 500.000, valued = 200.00;
  BigDecimal left_operand = new BigDecimal(valueD),
  right_operand = new BigDecimal(valued),
  result = new BigDecimal(0);

  result = left_operand.subtract(right_operand);
  System.out.println(" \nleft operand value :" +
  " " + left_operand
  "\nright_operand value : " + right_operand
  "\nmethod generated value : " + result);

  valueD = 100.23;
  valued = 123;
  left_operand = new BigDecimal(valueD);
  right_operand = new BigDecimal(valued);
  result = new BigDecimal(0);

  result = left_operand.subtract(right_operand);
  System.out.println(" \nleft operand value : "
  + left_operand
  "\nright_operand value : " + right_operand
  "\nmethod generated value : " + result);

  }
}
