&引用；插入AssignmentOperator表达式“；错误JAVA

我不断收到错误“Insert AssignmentOperator expression to complete expression”我的程序基本上是选择动物所在的随机位置。我也在写数组和变量，对吗

问题出现在if语句中；具体代码为girafflocation[r.nextInt（girafflocation.length）]

实际上，您并没有将随机位置的查找存储在任何位置，您希望这样：

String tmp = giraffeLocation [r.nextInt(giraffeLocation.length)];

System.out.println("Your giraffe is in, " + tmp );

固定代码应该是这样的

   public static void main(String[] args){
        Scanner s = new Scanner(System.in);
        Random r = new Random();

        String[] giraffeLocation;
        giraffeLocation = new String[3];
        giraffeLocation[0] = ("Africa");
        giraffeLocation[1] = ("Russia");
        giraffeLocation[2] = ("Germany");

        System.out.println("Welcome to the animal tracker!");
        try { Thread.currentThread().sleep(800); }
        catch ( Exception e ) { }

        System.out.println("Which animal shall we be tracking today?");
        try { Thread.currentThread().sleep(800); }
        catch (Exception e) { }

        System.out.println("\nGiraffe?\nRhino?\nHipopotamus?");
        String animal = s.nextLine();
            if(animal.equalsIgnoreCase("giraffe")){
                String location = "";
                try {
                     location = giraffeLocation [r.nextInt(giraffeLocation.length)];
                } catch (Exception e) {
                    System.out.println("EXCEPTIION");
                }                  
                System.out.println("Your giraffe is in, " + location );
            }
    }

看起来你忘记了对arraygiraffeLocation[r.nextInt（giraffeLocation.length）]中该索引处的值做些什么了。你想在这里实现什么？@PradeepSimha我正试图从giraffeLocation数组打印出一个随机位置到控制台。但每次都有不同的位置。@user2548682，下面的答案是正确的。您没有将其存储到任何变量，因此您得到的是上述错误。

   public static void main(String[] args){
        Scanner s = new Scanner(System.in);
        Random r = new Random();

        String[] giraffeLocation;
        giraffeLocation = new String[3];
        giraffeLocation[0] = ("Africa");
        giraffeLocation[1] = ("Russia");
        giraffeLocation[2] = ("Germany");

        System.out.println("Welcome to the animal tracker!");
        try { Thread.currentThread().sleep(800); }
        catch ( Exception e ) { }

        System.out.println("Which animal shall we be tracking today?");
        try { Thread.currentThread().sleep(800); }
        catch (Exception e) { }

        System.out.println("\nGiraffe?\nRhino?\nHipopotamus?");
        String animal = s.nextLine();
            if(animal.equalsIgnoreCase("giraffe")){
                String location = "";
                try {
                     location = giraffeLocation [r.nextInt(giraffeLocation.length)];
                } catch (Exception e) {
                    System.out.println("EXCEPTIION");
                }                  
                System.out.println("Your giraffe is in, " + location );
            }
    }
