इस लेख में हम समझेंगे कि Java में कैसे जांचें कि कोई स्ट्रिंग किसी सबस्ट्रिंग को समाहित करती है या नहीं। स्ट्रिंग एक डेटा टाइप है जिसमें एक या अधिक कैरेक्टर होते हैं और यह डबल कोट्स (" ") में संलग्न होता है। स्ट्रिंग का एक भाग या उपसमुच्चय सबस्ट्रिंग कहलाता है।
उदाहरण
इनपुट:
The first substring is defined as: Java The second substring is defined as: C++
आउटपुट:
The substring: Java is a part of the defined string. The substring: C++ is not a part of the defined string.
एल्गोरिदम
- शुरुआत
- तीन स्ट्रिंग्स डिक्लेयर करें:
input_string,sub_string_1,sub_string_2 - मान परिभाषित करें
.contains()फंक्शन का उपयोग करके जांचें कि स्ट्रिंग में सबस्ट्रिंग है या नहीं- परिणाम प्रदर्शित करें
- रोकें
उदाहरण 1: मुख्य फंक्शन में सभी ऑपरेशन
public class Demo {
public static void main(String[] args) {
String input_string = "Java Programming";
System.out.println("The input string is defined as: " + input_string);
String sub_string_1 = "Java";
System.out.println("The first substring is defined as: " + sub_string_1);
String sub_string_2 = "C++";
System.out.println("The second substring is defined as: " + sub_string_2);
boolean result = input_string.contains(sub_string_1);
if(result) {
System.out.println("The substring: " + sub_string_1 + " is a part of the defined string.");
} else {
System.out.println("The substring: " + sub_string_1 + " is not a part of the defined string.");
}
result = input_string.contains(sub_string_2);
if(result) {
