Case sensitive comparison
Compare strings using firstString.compareTo(secondString). Positive outcome means firstString > secondString and so on.
public class Main {
public static void main(String[] args) {
String firstStr = "def";
String[] secondStrArr = {"abc", "def", "efg", "DEF"};
System.out.println("firstStr | secondStr | firstStr.compareTo(secondStr)");
for (String secondStr: secondStrArr) {
System.out.println(firstStr + " | "+ secondStr + " | " + firstStr.compareTo(secondStr));
}
}
}firstStr | secondStr | firstStr.compareTo(secondStr) def | abc | 3 def | def | 0 def | efg | -1 def | DEF | 32
Case insensitive comparison – compareToIgnoreCase
public class MainIgnoreCase {
public static void main(String[] args) {
String firstStr = "def";
String[] secondStrArr = {"abc", "def", "efg", "DEF"};
System.out.println("firstStr | secondStr | firstStr.compareToIgnoreCase(secondStr)");
for (String secondStr: secondStrArr) {
System.out.println(firstStr + " | "+ secondStr + " | " + firstStr.compareToIgnoreCase(secondStr));
}
}
}firstStr | secondStr | firstStr.compareToIgnoreCase(secondStr) def | abc | 3 def | def | 0 def | efg | -1 def | DEF | 0
