BigDecimal min() Method in Java

The java.math.BigDecimal.min(BigDecimal val) method in Java is used to compare two BigDecimal values and return the minimum of the two.

Syntax:

public BigDecimal min(BigDecimal val)

Parameters: The function accepts a BigDecimal object val as parameter whose value is compared with that of this BigDecimal object and the minimum value is returned.



Return Values: This method returns the BigDecimal whose value is the smaller of this BigDecimal and val. In case if both are equal, this BigDecimal is returned.

Examples:

Input :  a = 17.000041900, b = 17.0000418999
Output : 17.0000418999

Input : a = 235900000146, b = 236000000000
Output : 235900000146

                        " and " + b + " is " + a.min(b));
    }
}

Output:

Minimum Value among 17.000041900 and 17.0000418999 is 17.0000418999

Output:

Length of string GeeksforGeeks is 13
Length of string GeeksClasses is 12
Minimum length is 12
