Java String Exercises: Check whether a given string starts with the contents of another string

Java String : Exercise-26 with Solution

Write a Java program to check whether a given string starts with the contents of another string.

Sample Solution:

Java Code:

public class Exercise26 {
    
   public static void main(String[] args)
    {
        String str1 = "Red is favorite color.";
        String str2 = "Orange is also my favorite color.";

        // The String to check the above two Strings to see
        // if they start with this value (Red).
        String startStr = "Red";

        // Do either of the first two Strings start with startStr?
        boolean starts1 = str1.startsWith(startStr);
        boolean starts2 = str2.startsWith(startStr);

        // Display the results of the startsWith calls.
        System.out.println( str1 + " starts with " +
             startStr + "? " + starts1);
        System.out.println(str2 + " starts with " +
             startStr + "? " + starts2);
    }
}

Sample Output:

Red is favorite color. starts with Red? true                                                                  
Orange is also my favorite color. starts with Red? false

Java Code Editor:

public class Exercise26 {
    
   public static void main(String[] args)
    {
        String str1 = "Red is favorite color.";
        String str2 = "Orange is also my favorite color.";

        // The String to check the above two Strings to see
        // if they start with this value (Red).
        String startStr = "Red";

        // Do either of the first two Strings start with startStr?
        boolean starts1 = str1.startsWith(startStr);
        boolean starts2 = str2.startsWith(startStr);

        // Display the results of the startsWith calls.
        System.out.println( str1 + " starts with " +
             startStr + "? " + starts1);
        System.out.println(str2 + " starts with " +
             startStr + "? " + starts2);
    }
}
