        List<String> str1List = str1.split(';');
        List<String> str2List = str2.split(';');
        for(Integer i=0;i<str1List.size();i++){
            if(str2List.contains(str1List[i])){
                system.debug('Yes this word '+str1List[i]+' is contains in str2List');

Hello, if you want to compare the two strings as is, you can just do like this:  
String str1 = 'Pay TV;AVOD;Basic TV';
String str2 = 'Basic TV;Pay TV;AVOD';

system.debug(str1 == str2); // false

However if you would like to compare each values in the string to see if they are the same, you could do something like this: 
String str1 = 'Pay TV;AVOD;Basic TV';
String str2 = 'Basic TV;Pay TV;AVOD';

List<String> str1List = str1.split(';');
List<String> str2List = str2.split(';');
Boolean valuesAreTheSame = true;
for(String tmp1 : str1List){
    if(!str2List.contains(tmp1)){
       valuesAreTheSame = false; 
    }
}

if(valuesAreTheSame){
    system.debug('Values in the two strings are the same.');
} else {
    system.debug('Values in the two strings are not the same.');
}

HI Anil Kumar,
Try using the String.equals() method within Apex. It does a string comparison but it is case-sensitive. 
String myString1 = 'abcd';
String myString2 = 'abcd';
Boolean result =  myString1.equals(myString2);
System.debug(result);
Try using the String.equalsIgnoreCase() method within Apex. It does a string comparison, it is not case-sensitive. 
String myString1 = 'abCD';
String myString2 = 'abcd';
Boolean result =  myString1.equalsIgnoreCase(myString2);
System.debug(result);
