Java Set<String> equality ignore case
ignore-case, java, set
Solution
Alternatively you can use `TreeSet`.
public static void main(String[] args){
Set<String> s1 = new TreeSet<String>(String.CASE_INSENSITIVE_ORDER);
s1.addAll(Arrays.asList(new String[] {"a", "b", "c"}));
Set<String> s2 = new TreeSet<String>(String.CASE_INSENSITIVE_ORDER);
s2.addAll(Arrays.asList(new String[] {"A", "B", "C"}));
System.out.println(s1.equals(s2));
}
Problem
I want to check if all elements of two sets of String are equal by ignoring the letter's cases. ``` Set<String> set1 ; Set<String> set2 ; . . . if(set1.equals(set2)){ //all elements of set1 are equal to set2 //dosomething } else{ //do something else } ``` However, this equality check doesn't ignore the cases of the string. Is there some other way of doing that?
