Is the Security Exception that comes from the java.lang package a checked exception or an unchecked one? What about an exception that says there is no such method?
Let's revisit chapter 5 example, but this time, no method can throw any exception out of the method and if an exception was detected then you will have to throw your own custom exception to let the user know what happened.
public class Chapter11Demo{ public static void main(java.lang.String[] args) {method1();}private static void method1(){ method2();}private static void method2(){ method3();}private static void method3(){ method4();}private static void method4(){ method5();}private static void method5(){ method6();}private static void method6(){ java.io.File in=new java.io.File("somefile.txt"); java.io.File out=new java.io.File("somefile2.txt"); java.util.Scanner inFile=new java.util.Scanner(in); java.io.FileWriter outFile=new java.io.FileWriter(out); }}
Is the SecurityException type a checked or unchecked exception in the java.lang package? Must we not throw NoSuchMethodException? Be sure to provide reasons for your answers.
