check if two strings are equal in java 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 know if String is the same java

String1.equals(String2)

Example 4: java test if strings are equal

//This expression is true if str1 and str2 are equal, and false if they're not
str1.equals(str2)

//example use case:
String location = "London";
String destination = "London";
if (location.equals(destination)) {
	System.out.println("You have arrived!");
}

Example 5: check if two strings are equal 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 6: check if two strings are equal in java

{
   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));
   }
