// Darur
public class ArraylistDemo {
public ArrayList addValuesInArrayList ( ){
ArrayList arrayList = new ArrayList( );
arrayList.add( "Bria " );
arrayList.add( "Bria " );
arrayList.add( "TI " );
arrayList.add( "TI " );
arrayList.add( "CL " );
arrayList.add( "CL " );
arrayList.add( "CLA " );
arrayList.add( "VENU " );
arrayList.add( "GOPAL" );
arrayList.add( "NARAYANA " );
arrayList.add( "JANAKI RAM " );
arrayList.add( "VASAVI " );
return arrayList;
}
//
public void printValuesInArrayList( ArrayList arrayList ){
System.out.println( "--------USING FOR
ITERATOR------------" );
Iterator iterator = arrayList.iterator();
while( iterator.hasNext() ){
String name = ( ( String ) iterator.next() ).toUpperCase();
System.out.println( "Name: " + name );
}
System.out.println( "--------USING FOR
ITERATOR------------" );
}
//
public void printValuesInArrayListUsingForLoop( ArrayList
arrayList ){
System.out.println( "--------USING FOR LOOP
START------------" );
for( int i = 0 ; i < arrayList.size() ; i++ ){
String name = ( ( String ) arrayList.get( i ) ).toUpperCase();
System.out.println( "Name: " + name );
}
System.out.println( "--------USING FOR LOOP
END------------" );
}
public static void main ( String [] args ){
ArraylistDemo arraylistDemo = new ArraylistDemo( );
ArrayList arrayList = arraylistDemo.addValuesInArrayList();
arraylistDemo.printValuesInArrayList(arrayList);
arraylistDemo.printValuesInArrayListUsingForLoop(arrayList);
}
}
output of the program may be like this:
-------USING FOR ITERATOR------------
Name: BRIA
Name: BRIA
Name: TI
Name: TI
Name: CLA
Name: CLA
Name: CLAY
Name: VENU
Name: GOPAL
Name: NARAYANA
Name: JANAKI RAM
Name: VASAVI
--------USING FOR ITERATOR------------
--------USING FOR LOOP START------------
Name: BRIA
Name: BRIA
Name: TI
Name: TI
Name: CLA
Name: CLA
Name: CLA
Name: VENU
Name: GOPAL
Name: NARAYANA
Name: JANAKI RAM
Name: VASAVI
--------USING FOR LOOP END------------
