Example

public static void main( String[] args ) {

for ( int i = 0; i < args.length; i++ ){
try {
System.out.println( Integer.parseInt( args[ i ] ) );
} catch ( NumberFormatException e ){
throw new IllegalArgumentException( e.getMessage() );
}
}
}

Solution
Move the try/catch blocks outside of the loop.

public static void main( String[] args ) {

try {
for ( int i = 0; i < args.length; i++ ){
System.out.println( Integer.parseInt( args[ i ] ) );
}
} catch ( NumberFormatException e ){
throw new IllegalArgumentException( e.getMessage() );
}

}
