示例

public static class ClassA implements Iterator {
//Other Iterator methods...
public Object next () {

try {
//...
} catch ( Exception e ) {
// Handle exceptions here
}
}

}


解决方案
重新考虑 catch 子句的功能。确保在出现错误时抛出 java.util.NoSuchElementException


public static class ClassA implements Iterator {
//Other Iterator methods...
public Object next() {

try {
//...
} catch ( Exception e ) {
throw new NoSuchElementException();
}
}
return nextObj;
}
