java - multiply large no. in array -


multiply 2 numbers. numbers can extremely large (i.e. run hundreds of digits) , provided strings.

the expected output string represents product of 2 numbers. example-

multiply("268435456","524288")="140737488355328" multiply("12321412423524534534543","0")="0"

use bigdecimal, has multiply method , constructor takes string. contains corresponding tostring() , toplainstring() methods result string.

(if numbers whole numbers, use biginteger instead.)
