Return type int. Returns the index of the first occurrence of ch in the string. Returns-1 if not matched. import java.lang.String; class indexof{                         public static void main(String[] args){                          String str="Welcome to java";                         int i="welcome".indexOf('l');                        System.out.println("Index of l in \" "+str+"\"  is : "+i);                      } } Output :    Index of l in "Welcome to java is : 2
