Question

Util class in java can be made in two ways

class Utils  
{   
  public static ReturnType someUtilMethod(  
 // ...   
}    

and execute util method by

Utils.someUtilMethod(...);

Or I can make

class Utils  
{  
  public Utils(){}     
  public ReturnType someUtilMethod(  
 // ...   
}  

and execute util method by

new Utils().someUtilMethod(...)  

What way is better? Are some differences between this ways?

Answer 1

Generally Util class contains Utility methods which doesn’t need to store the state of Object to process and so static methods are good fit there
