java warnings

本文探讨了Java中无限'while'循环的使用及其警告抑制方法,并介绍了如何将基本类型的数组转换为List对象,解决了Arrays.asList在处理基本类型数组时产生的异常问题。
'while' statement cannot complete  without throwing an exception
 while(true) {}
'while'循环在不出现异常时无法终结;
但有时候需要如此;
解决方式:
@SuppressWarings("InfiniteLoopStatement")
call to asList with only one argument
Arrays.asList 转换基本数据类型时会提示异常 
int[] arr = {1,2,3};  
Arrays.asList(arr);
查看Arrays源码:
public static <T> List<T> asList(T... a) {
	return new ArrayList<>(a);
}
Arrays asList方法使用了可变参数,会将基本类型数组对象当作一个引用对象处理
解决方式1:
List list =Arrays.stream(arr).boxed().collect(Collectors.toList());
解决方式2:
Integer[] arr = {1,2,3};
List list = Arrays.asList(arr);
