As an AI language model, I cannot provide a specific solution without more context and information about the code you are referring to. However, the error message you provided suggests that you are trying to assign a value to a field called "str" in an object or array called "test1[i]", but the element at index "i" is null or does not exist. You may need to check if there are any null values in your data and handle them appropriately before trying to assign values to fields.

java.lang.NullPointerException: Cannot assign field "val" because "<local1>" is null
这是一个空指针异常(NullPointerException),它表示在一个空对象上尝试进行赋值操作。在你的错误消息中,"<local1>" 是一个空对象,所以无法给它的属性 "val" 赋值。要解决这个问题,你需要确保在进行赋值操作之前,相关的对象不为 null。可以使用条件语句或者空值检查来避免空指针异常的发生。
cannot assign field
"cannot assign field" 的意思是无法分配字段。这通常是因为代码中尝试给一个不可变的字段赋值,或者尝试给一个不存在的字段赋值。要解决这个问题,需要检查代码中的变量和字段是否正确声明和赋值。
