Java String compareTo() Example Code

class Main {
 public static void main(String[] args) {
   String str1 = "Learn Java";
   String str2 = "Learn Java";
   String str3 = "Learn Kolin";
   int result;
   // comparing str1 with str2
   result = str1.compareTo(str2);
   System.out.println(result);  // 0
   // comparing str1 with str3
   result = str1.compareTo(str3);
   System.out.println(result);  // -1
   // comparing str3 with str1
   result = str3.compareTo(str1);
   System.out.println(result);  // 1
 }
}
 
Example 2: Check if Two Strings are Equal
class Main {
 public static void main(String[] args) {
   String str1 = "Learn Python";
   String str2 = "Learn Java";
       
   // if str1 and str2 are equal, the result is 0
   if (str1.compareTo(str2) == 0) {
     System.out.println("str1 and str2 are equal");
   }
   else {
     System.out.println("str1 and str2 are not equal");
   }
 }
}
