Given: 10. public class Bar { 11. static void foo( int... x ) { 12. // insert code here 13. } 14. } Which two code fragments, inserted independently at line 12, will allow the class to compile? (Choose two.)
foreach( x ) System.out.println(z);
for( int z : x ) System.out.println(z);
while( x.hasNext() ) System.out.println( x.next() );
for( int i=0; i< x.length; i++ ) System.out.println(x[i]);
