java.text.setMaximumIntegerDigits works incorrectly.

Name: dfC67450 Date: 02/10/98



java.text.setMaximumIntegerDigits takes into account only the
lowest 8 bits of the argument.

The bug causes the following JCK-12beta2 test to fail:

api/java_text/NumberFormat/manual.html#SetGet


Here is the test demonstrating the bug:

-----------------TestNF.java------------------------
import java.text.*;

public class TestNF {
    public static void main (String args[]){
        NumberFormat nf = NumberFormat.getInstance();
        nf.setMaximumIntegerDigits(128);
        System.out.println("setMaximumIntegerDigits(128)");
        System.out.println("getMaximumIntegerDigits() returns " + nf.getMaximumIntegerDigits());
    }
}

---------Output from the test---------------------
setMaximumIntegerDigits(128)
getMaximumIntegerDigits() returns -128
--------------------------------------------------

Javadoc is silent about range of input values which the
  java.text.NumberFormat.setMaximumIntegerDigits(int newValue),
  java.text.NumberFormat.setMinimumIntegerDigits(int newValue),
  java.text.NumberFormat.setMaximumFractionDigits(int newValue),
  java.text.NumberFormat.setMinimumFractionDigits(int newValue)

allow. (See 4075780) These methods shouldn't probably convert
int to byte.

Here is the fragment of source code for setMaximumIntegerDigits method:

    /**
     * Sets the maximum number of digits allowed in the integer portion of a
     * number. maximumIntegerDigits must be >= minimumIntegerDigits. If the
     * new value for maximumIntegerDigits is less than the current value
     * of minimumIntegerDigits, then minimumIntegerDigits will also be set to
     * the new value.

     * @see #getMaximumIntegerDigits
     */
    public void setMaximumIntegerDigits(int newValue) {
        maxIntegerDigits = (byte) Math.max(0,Math.min(newValue,308));
        if (minIntegerDigits > maxIntegerDigits)
            minIntegerDigits = maxIntegerDigits;
    }
