compare strings code example

Example 1: java how to compare strings

System.out.println("hey".equals("hey")); //prints true

/*
	always use .equals() instead of ==,
    because == does the compare the string content but
    loosely where the string is stored in.
*/

Example 2: Java compare two strings

// compare two strings in java using String.equals() method in java
public class EqualsMethodDemo
{
   public static void main(String[] args)
   {
      String str1 = new String("HelloWorld");
      String str2 = new String("Flower");
      String str3 = new String("Hello");
      String str4 = new String("Hello");
      String str5 = new String("hello");
      // compare str1 != str2
      System.out.println("Compare " + str1 + " and " + str2 + ": " + str1.equals(str2));
      // compare str3 = str4
      System.out.println("Compare " + str3 + " and " + str4 + ": " + str3.equals(str4));
      // compare str4 != str5
      System.out.println("Compare " + str4 + " and " + str5 + ": " + str4.equals(str5));
      // compare str1 != str4
      System.out.println("Compare " + str1 + " and " + str4 + ": " + str1.equals(str4));
   }
}

Example 3: how to check to string are qual r not

String str1 = "rohith";
String str2 = "nikhil";
//compares if str1(rohith) is equal to str2(nikhil)
System.out.println(str1.equals(str2));
//prints false as str1!=str2

Example 4: how to compare strings java

if (aName.equals(anotherName))
        { 
            System.out.println(aName + " equals " + anotherName);
        }
        else 
            { 
                System.out.println(aName + " does not equal " +anotherName );
                           
            }

Example 5: compare two strings java

String string1 = "using equals method";String string2 = "using equals method";        String string3 = "using EQUALS method";String string4 = new String("using equals method"); assertThat(string1.equals(string2)).isTrue();assertThat(string1.equals(string4)).isTrue(); assertThat(string1.equals(null)).isFalse();assertThat(string1.equals(string3)).isFalse();
