Method Definition: int indexOf(String str, int fromIndex)
Return Type: It returns the index of the sub-string from the index specified in the argument.

Example #1:

// Scala program of int indexOf() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Applying indexOf method 
        val result = "Nidhisinghis".indexOf("his", 4) 
          
        // Displays output 
        println(result) 
      
    } 
}
