如何列出保存在哈希图中的对象中存在的值
我试图查看是否可以列出我保存在对象上的值，并将其存储在哈希图中，但是我不知道是否有可能检索这些值

基本上我的问题和这个人Displaying object values which are stored in a HashMap一样，然后就可以解决
答案 0 :(得分：1)
正如@Lutz Horn在评论中所写，您可以使用set.seed(123)
dd <- data.frame(matrix(sample(1:2, 10*3, TRUE), ncol = 3), "fv" = gl(2, 5,labels = letters[1:2]))
unique(dd) # 7 unique rows with all variables
#> X1 X2 X3 fv
#> 1 1 2 2 a
#> 2 2 1 2 a
#> 4 2 2 2 a
#> 6 1 2 2 b
#> 7 2 1 2 b
#> 9 2 1 1 b
#> 10 1 2 1 b
col_dup <- names(dd)[1:3] # set which set of columns to get duplicated from
# unique(dd[,col_dup]) # what you expect in final for those rows
ind_dup <- duplicated(dd[,col_dup]) # get index of duplicated elements
new_dd <- dd[!ind_dup,]
new_dd
#> X1 X2 X3 fv
#> 1 1 2 2 a
#> 2 2 1 2 a
#> 4 2 2 2 a
#> 9 2 1 1 b
#> 10 1 2 1 b
方法来检索哈希图的值。
values()答案 1 :(得分：0)
hashUser.values（）返回hashUser值的集合。
迭代器userIterator = hashUser.values（）。iterator（）;
使用Java 8 userIterator.forEachRemaining（System.out :: println）;
