arraytroubleagain.java

JAVA 工作指南 可以说是程序员必备的东西哦

import java.lang.reflect.Array;
import static java.lang.System.err;

public class ArrayTroubleAgain {
    public static void main(String... args) {
	Integer[] ary = new Integer[2];
	try {
	    Array.setInt(ary, 0, 1);  // IllegalArgumentException

        // production code should handle these exceptions more gracefully
	} catch (IllegalArgumentException x) {
	    err.format("Unable to box%n");
	} catch (ArrayIndexOutOfBoundsException x) {
	    x.printStackTrace();
	}
    }
}
