该错误can only iterate over an array or an instance of java.lang.iterable的实例并不意味着它会阻止用户在数组或实例上使用循环。 这意味着使用的循环不能补充其条件 - 例如 for 或 foreach 循环。 使用Iterator() 解决 Can Only Iterate Over an Array or an Instance of java.lang.iterable 错误 在循环...
这条错误信息表明,在Java中,你只能对数组(Array)或实现了java.lang.Iterable接口的对象进行迭代操作。如果你尝试对一个不符合这些条件的对象进行迭代(例如,一个普通的对象或者一个基本数据类型),编译器就会抛出这个错误。 提供可能导致这个错误的常见原因 尝试对非Iterable或数组类型进行for-each循环:例如,尝试对一个普...
