异常处理——抛出异常
代码如下：
package Day09;
public class TestInt { public static void main(String[] args) {
int num = Integer.MAX_VALUE-1;
System.out.println(num);
try {
num = intAddOne(num);
} catch (Exception e) {
e.printStackTrace();
}
System.out.print(num);
}
private static int intAddOne(int number) throws Exception {
if (number >= Integer.MAX_VALUE) {
throw new Exception("Int max value reached");
}
return ++number;
}
}
