Best way to compare string in java
2) regionMatches()The Show
3) startsWith() and endsWith()The This method is case sensitive.
4) equals() vs. ==We often get confused while using The
5) compareTo()The
A string is said to be greater when it comes after the other in the dictionary, and lesser when it comes before the other in the dictionary. This method is case sensitive. In this program, you'll learn to compare two strings in Java. To understand this example, you should have the knowledge of the following Java programming topics:
Example 1: Compare two strings
Output Equal In the above program, we've two strings style and style2. We simply use the equal to operator ( Example 2: Compare two strings using equals()
Output Equal In the above program, we have two strings named style and style2 both containing the same world Bold. However, we've used You should not use On the other hand, If you instead change the program to use equality operator, you'll get Not Equal as shown in the program below. Example 3: Compare two string objects using == (Doesn't work)
Output Not Equal Example 4: Different ways to compare two stringsHere is the string comparison which is possible in Java.
Output true false false true Can I use == to compare strings in Java?You should not use == (equality operator) to compare these strings because they compare the reference of the string, i.e. whether they are the same object or not. On the other hand, equals() method compares whether the value of the strings is equal, and not the object itself.
Should I use .equals or == Java?We can use == operators for reference comparison (address comparison) and . equals() method for content comparison. In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects.
Which method is used to compare two strings Java?Using String. equals() :In Java, string equals() method compares the two given strings based on the data/content of the string.
Which method is used to compare to strings?The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings.
