Java Program to Perform String Matching Using Vectors

This is a java program to perform search using Vectors.

Here is the source code of the Java Program to Implement String Matching Using Vectors. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
 
```
```
package com.sanfoundry.setandstring;
```
```
 
```
```
import java.util.Scanner;
```
```
import java.util.Vector;
```
```
 
```
```
public class StringSearchUsingVectors
```
```
{
```

    public static void main(String[] args)

```
    {
```

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter the main string: ");

        Vector<String> text = new Vector<String>();

```
        text.add(sc.nextLine());
```

        System.out.println("Enter the pattern string: ");

        Vector<String> pattern = new Vector<String>();

```
        pattern.add(sc.nextLine());
```

        for (int i = 0; i <= text.elementAt(0).length()

                - pattern.elementAt(0).length(); i++)

```
        {
```
```
            if (text.elementAt(0)
```

                    .substring(i, i + pattern.elementAt(0).length())

                    .equalsIgnoreCase(pattern.elementAt(0)))

```
            {
```

                System.out.println(pattern.elementAt(0)

                        + " is substring of main string, match found at: "

```
                        + ++i);
```
```
            }
```
```
        }
```
```
        sc.close();
```
```
    }
```
```
}
```

Output:

$ javac StringSearchUsingVectors.java
$ java StringSearchUsingVectors
 
Enter the main string: 
Java Program to Implement String Matching Using Vectors
Enter the pattern string: 
Vectors
Vectors is substring of main string, match found at: 49
