Java Program to find all subsets of a string

In this example, we will create a java program to find all the subsets of a given string and print them.

The subset of a string is the character or the group of characters that are present inside the given string. Any string can have n(n+1)/2 possible subsets.

Program:


public class Main 
{  
    public static void main(String[] args) 
	{  
 
        String str = "Abhimanyu";  
        int len = str.length();  
        int temp = 0;  
        String arr[] = new String[len*(len+1)/2];  
  
        for(int i = 0; i < len; i++) 
		{  
            for(int j = i; j < len; j++) 
			{  
                arr[temp] = str.substring(i, j+1);  
                temp++;  
            }  
        }  
  
        System.out.println("All subsets for given string are: ");  
        for(int i = 0; i < arr.length; i++) 
		{  
            System.out.println(arr[i]);  
        }  
    }  
}
