final class Tree { private static String tree = "tree "; String getTree() { return tree; } } class Elm extends Tree { private static String tree = "elm "; public static void main(String [] args) { new Elm().go(new Tree()); } void go(Tree t) { String s = t.getTree()+Elm.tree+tree+(new Elm().getTree()); System.out.println(s); } } 結(jié)果為:()
public boolean a(int a,int b){return a==b;}
現(xiàn)有: class Number{ public static void main(String [] aras) { try { System.out.print (Integer.parselnt ("forty")); } catch (RuntimeException r) { System.out.print ("runtime"); } catch (NumberFormatException e) { system..ut.print("number"); } } } 結(jié)果是什么?()
執(zhí)行以下代碼段,循環(huán)體會執(zhí)行()次。
