Hi rahul,
Try this code 
public class anagramCheck {
    public boolean check(string s1,string s2){
        boolean isAnagram = false;
        if(s1.length()==s2.length()){
            string[] sarray1 = s1.split('');//split string to chars
            string[] sarray2 = s2.split('');
            sarray1.sort();
            sarray2.sort();
            if(sarray1 == sarray2 ){
                isAnagram = true;
                system.debug(isAnagram);
                
            }
            
        }
        return isAnagram;
    }
    
}

Hope this helps you

You can utilize the below code if you want to find and print all anagrams in a given string. Please copy-paste below code in anonymous window to test.

 

//creating anagram input data.
List<String> inputArray = new List<String>{'cat', 'dog', 'tac', 'god', 'act'};
    
    //Code to check every two combinations of input array
    Map<Integer,Set<Integer>> mp = new Map<Integer,Set<Integer>>();  
    for(Integer i=0;i<inputArray.size();i++){
        for(Integer j=i+1;j<inputArray.size();j++){
        IsAnagram(inputArray[i],inputArray[j]);
       }     
    } 
    //Code to print Result
    system.debug('res1>'+mp);
    for(Integer i :mp.keyset()){
        Set<Integer> templist1 = mp.get(i);
        for(Integer j :templist1){
            system.debug('Result>'+inputArray.get(j));
        }
    }
    
    //Method to check if two numbers are anagram and store them using hashcode to print together later
    public Boolean IsAnagram(String a, String b){
        Boolean isAna = False;
        if(a.length() == b.length())
        {    
        string[] sarray1 = a.split('');
        string[] sarray2 = b.split('');    
            sarray1.sort();
            sarray2.sort();
            if(sarray1 == sarray2){
                isAna = True;
                string temps1 = String.join(sarray1,'');
                string temps2 = String.join(sarray2,'');
                Integer h1 = temps1.hashcode();
                Integer h2 = temps1.hashcode();
                if(mp.containsKey(h1)) {
                    Set<Integer> index = mp.get(h1);
                    index.add(inputArray.indexOf(a));index.add(inputArray.indexOf(b));
                    mp.put(h1, index);
                } else {
                    Integer x = inputArray.indexOf(a);
                    Integer y = inputArray.indexOf(b);
                    mp.put(h1, new Set<Integer> {x,y});
                }
                 
            }
        }
        return isAna;
    
    }
