考慮下面的代碼 public class Foo
{
int value;
public Foo (final String str, Object ... bug)
{
System.out.println ("Should work! 1");
}
public Foo (final String str, final int
class Test{
public static void main(String[] args){
int a = 1;
int b = 5;
Integer c = new Integer(1);
Integer d = 5; //autoboxing at work
System.out.println(c.comp
我有一個Java類的形式如下： class Example {
private byte[][] data;
public Example(int s) { data = new byte[s][s]; }
public byte getter(int x, int y) { return byte[x][y]; }
public void set
這將打印假 List vowelsList=Arrays.asList(new char[]{'a','e','i','o','u'});
System.out.println(vowelsList.contains('a'));//false
這將打印真正 List vowelsList=Arrays.asList(new Character[]{'a','e','i','o','u'})
