list String转double

[26.95,26.55,25.6,24.55,26.65,28.5,29.75,27.7,24.45,27.1,28.5,31.0,32.4,29.85,29.35,28.2,29.2,29.3,29.1,29.5,30.4,31.35]
[18.9,20.53,16.98,11.99,13.74,21.98,20.53,21.73,22.48,24.61,17.23,17.3,22.98,23.86,22.61,22.99,23.86,13.68,17.49,26.14,27.99,29.74]

将这两个list中的数字转成double

list.stream().map(Double::valueOf).collect(Collectors.toList());

写个for循环然后转一下不就行了么

String str="123456";

double d=Double.valueOf(str).doubleValue();

List doubleList = <span class="hljs-built_in">new</span> ArrayList<<span class="hljs-type">Double</span>>
循环list
<span class="hljs-type">Double</span> <span class="hljs-type">double</span> = <span class="hljs-type">Double</span>.valueOf("非null字符串");
doubleList.<span class="hljs-keyword">add</span>(<span class="hljs-type">double</span>)
