不，没有使用goto，但是您可以定义标签并留下一个到标签的循环。您可以使用break或continue后跟标签。所以你可以跳出多个循环层。看看教程。

是的，这是可能的，但不像在c#(在我看来，c#更好!)那些总是模糊软件的观点是愚蠢的!很遗憾java没有至少goto case xxx。

跳转向前:

 public static void main(String [] args) {
   myblock: {
     System.out.println("Hello");
     if (some_condition)
       break myblock; 
     System.out.println("Nice day");
   }
   // here code continue after performing break myblock
   System.out.println("And work");
 }

向后跳:

 public static void main(String [] args) {
   mystart: //here code continue after performing continue mystart
   do {
     System.out.println("Hello");
     if (some_condition)         
       continue mystart; 
     System.out.println("Nice day");
   } while (false);
   System.out.println("And work");
 }

关键字存在，但没有实现。

我能想到的使用goto的唯一好理由是:

for (int i = 0; i < MAX_I; i++) {
    for (int j = 0; j < MAX_J; j++) {
        // do stuff
        goto outsideloops; // to break out of both loops
    }
}
outsideloops:

在Java中，你可以这样做:

loops:
for (int i = 0; i < MAX_I; i++) {
    for (int j = 0; j < MAX_J; j++) {
        // do stuff
        break loops;
    }
}

关键字const和goto是 矜持，尽管事实并非如此 目前使用。”

不，goto在Java中没有使用，尽管它是一个保留字。对于const也是如此。这两个都在c++中使用，这可能是它们被保留的原因;这样做的目的可能是为了避免让迁移到Java的c++程序员感到困惑，也可能是为了在以后的Java版本中保留使用它们的选项。

它们被保留以供将来使用(请参阅:Java语言关键字)

关键字const和goto是保留的，即使它们目前没有被使用。

Java中没有goto语句的原因可以在“Java语言环境”中找到:

Java has no goto statement. Studies illustrated that goto is (mis)used more often than not simply "because it's there". Eliminating goto led to a simplification of the language--there are no rules about the effects of a goto into the middle of a for statement, for example. Studies on approximately 100,000 lines of C code determined that roughly 90 percent of the goto statements were used purely to obtain the effect of breaking out of nested loops. As mentioned above, multi-level break and continue remove most of the need for goto statements.
