java.text.ChoiceFormat.ctor(double[], String[]) doesn't perform any checkings

Name: dfC67450 Date: 01/26/98



java.text.ChoiceFormat.ctor(double[] limits, String[] formats) does not check
whether lengths of input arrays are equal.

Javadoc says:

 * When creating a ChoiceFormat, you must specify an array of formats
 * and an array of limits. The length of these arrays must be the same.

Because of this an unexpected exception may be thrown if, for example,
formats.length < limits.length.

Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;

public class Test {
    public static void main (String args[]){
        double[] limits = {1, 2, 3};
        String[] formats = {"one", "two"};
        ChoiceFormat cf = new ChoiceFormat(limits, formats);
        System.out.println(cf.format(5));
    }
}

---------Output from the test---------------------
java.lang.ArrayIndexOutOfBoundsException: 2
        at java.text.ChoiceFormat.format(ChoiceFormat.java)
        at java.text.ChoiceFormat.format(ChoiceFormat.java)
        at java.text.NumberFormat.format(NumberFormat.java)
        at Test.main(Test.java:8)
