Solution:

public boolean sameStarChar(String str) {
  int index=0;
  boolean b=false;
  if(str.length()<=1 || str.indexOf("*")==-1 || str.equals("**")) 
     b=true;
    
  for(int i=1; i<str.length()-1;i++){
    index=str.indexOf("*",i);
    if(index!=-1 && index!=str.length()-1 ){
      if( str.charAt(index-1)==str.charAt(index+1) )
        b= true;
      else
        b=false;
    }   
   
  }
  return b;
}
