java how to 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: string compare java ==
// These two have the same value
new String("test").equals("test") // --> true
// ... but they are not the same object
new String("test") == "test" // --> false
// ... neither are these
new String("test") == new String("test") // --> false
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: string compare java
// These two have the same value
new String("test").equals("test") // --> true
// ... but they are not the same object
new String("test") == "test" // --> false
// ... neither are these
new String("test") == new String("test") // --> false
Example 6: how to know if String is the same java
String1.equals(String2)
