Question

This is a simple lab.   Add in the minor changes as documented in the Lab 6 Files and study the handling of exceptions.

The %u201Cmain%u201D tryit.java does not need to be edited.

Your output when finished should appear as:

I threw this

In finally

/ by zero

keep on running

_____________________________________________________________________

package tryit;

/**

*

* @author jv

*/

public class Tryit {

/**

* @param args the command line arguments

*/

//

// NO changes are required to tryit.java (ie. This file)

public static void main(String[] args)

{

Trouble trouble = new Trouble();

if( trouble.thisReturnsTrue()) LogFile.lg( "This is a simple test of the log file. ");

if( trouble.unexpectedResult() ) LogFile.lg( "UnexpectedResult returned True ");

else LogFile.lg( "UnexpectedResult returned False");

try{ trouble.throwBecauseICan(); }

catch( Exception e ) { S.m(e.getMessage() ); }

try{ trouble.divideByZero(); }

catch( Exception e1 ){ S.m( e1.getMessage()); }

S.m("keep on running");

}

}

Explanation / Answer

package tryit;

/**

*

* @author jv

*/

public class Tryit {

/**

* @param args the command line arguments

*/

//

// NO changes are required to tryit.java (ie. This file)

public static void main(String[] args)

{

Trouble trouble = new Trouble();

new LogFile();

if( trouble.thisReturnsTrue())

LogFile.lg( "This is a simple test of the log file. ");

if( trouble.unexpectedResult() ) LogFile.lg( "UnexpectedResult returned True ");

else LogFile.lg( "UnexpectedResult returned False");

try{ trouble.throwBecauseICan(); }

catch( Exception e ) { S.m(e.getMessage() ); }

try{ trouble.divideByZero(); }

catch( Exception e1 ){ S.m( e1.getMessage()); }

S.m("keep on running");

}

}

--------------------------------------------------------------------

package tryit;

public class Trouble

{

Trouble(){}

public boolean thisReturnsTrue(){ return true; }

public boolean unexpectedResult(){

try { return false;}

finally { return true; }

}

public boolean throwBecauseICan ()throws Exception {

try

{ S.m("I threw this"); }

finally

{ LogFile.lg(" throwBecauseICan ");}

return false;

}

void divideByZero() {

try{

two();

}

finally

{ S.m("In finally");}

}

void two()

{ int j;

for( int i = 1; i < 7; i-- )

{ j = i/i;}

}

}
