The **`contains()` method in Java** is used to search the substring in a given String. Returns: If the substring is found in the specified String, then it returns a true value; otherwise, it returns​ a false value.

# Syntax
```java
public boolean String.contains(CharSequence substring)
```

# Code
The same example that was shown above is given in the code snippet below. This method is *case-sensitive*.

class HelloWorld {
    public static void main( String args[] ) {
        String str = "Hello World"; 
  
        // prints true 
        System.out.println(str.contains("World")); 
  
        // prints false 
        System.out.println(str.contains("world")); 
    }
}
