Java Program to find all the permutations of a string

In this example, we will create a java program to find all the permutations of a given string.

Program:


public class Main 
{    
    public static String swapString(String a, int i, int j) 
	{    
        char[] b =a.toCharArray();    
        char ch;    
        ch = b[i];    
        b[i] = b[j];    
        b[j] = ch;    
        return String.valueOf(b);    
    }    
        
    public static void main(String[] args)    
    {    
        String str = "ABCD";    
        int len = str.length();    
        System.out.println("All the permutations of the string are: ");    
        generatePermutation(str, 0, len);    
    }    
        
    public static void generatePermutation(String str, int start, int end)    
    {    
        if (start == end-1)    
            System.out.println(str);    
        else    
        {    
            for (int i = start; i < end; i++)    
            {    
                str = swapString(str,start,i);    
                generatePermutation(str,start+1,end);    
                str = swapString(str,start,i);    
            }    
        }    
    }    
}

Output
All the permutations of the string are:
ABCD
ABDC
ACBD
ACDB
ADCB
ADBC
BACD
BADC
BCAD
BCDA
BDCA
BDAC
CBAD
CBDA
CABD
CADB
CDAB
CDBA
DBCA
DBAC
DCBA
DCAB
DACB
DABC
