find SUbstring in astring java code example
Example: find a substring in a string java
package hello;
public class SubStringProblem {
public static void main(String[] args) {
System.out
.println("Checking if one String contains another String using indexOf() in Java");
String input = "Java is the best programming language";
boolean isPresent = input.indexOf("Java") != -1 ? true : false;
if (isPresent) {
System.out.println("input string: " + input);
System.out.println("search string: " + "Java");
System.out.println("does String contains substring? " + "YES");
}
System.out.println("Doing search with different case");
isPresent = input.indexOf("java") != -1 ? true : false;
System.out.println("isPresent: " + isPresent);
System.out
.println("Checking if one String contains another String using contains() in Java");
input = "C++ is predecessor of Java";
boolean isFound = input.contains("Java");
if (isFound) {
System.out.println("input string: " + input);
System.out.println("search string: " + "Java");
System.out.println("does substring is found inside String? " + "YES");
}
System.out.println("Searching with different case");
isFound = input.contains("java");
System.out.println("isFound: " + isFound);
}
}
Output
Checking if one String contains another String using indexOf() in Java
input string: Java is the best programming language
search string: Java
does String contain substring? YES
Doing search with different case
isPresent: false
Checking if one String contains another String using contains() in Java
input string: C++ is the predecessor of Java
search string: Java
does substring is found inside String? YES
Searching for different case
isFound: false
