今天在人人上看到一張圖。
大體意思就是在下面代碼 if()的括弧中加入任意代碼,使之列印出"Hello World!":
public static void main(String[] args){
try {
if(){
System.out.print("Hello ");
}else{
System.out.println("world!");
}
} catch (Exception e) {
e.printStackTrace();
}
}
接下來是各路程式員各顯風騷的時刻:
1.
if(new Callable<Boolean>() {
public Boolean call() {
System.out.print("Hello ");
return false;
}
}.call()){
System.out.print("Hello ");
}else{
System.out.println("world!");
}
2.
if(new Object(){{System.out.print("Hello ");}} == null){
System.out.print("Hello ");
}else{
System.out.println("world!");
}
3.這個很有想法~
if(true)System.out.print("Hello "); if(false){
System.out.print("Hello ");
}else{
System.out.println("world!");
}
4.
if (System.out.append("Hello ")== null) {
System.out.print("Hello ");
} else {
System.out.println("world!");
}
5.
if(System.out.getClass().getDeclaredMethod("print", String.class).invoke(System.out, "Hello ") != null){
System.out.print("Hello ");
}else{
System.out.println("world!");
}
你還想到了哪些呢,歡迎共用~
