Public class Permutation {static int [] a; public Permutation (int [] a) {this.a = a;} public static void main (String [] args) {int a [] = new int [] {1, Permutation p = new Permutation (a); p.permutation (a) } private void permutation (int length, int start) {if (start = = length-1) {print (length);} else {for (int I = start; I < length;i++) {/ / for loop only comes in for the first time is I = start swap (iMagazine start); permutation (length,start+1); swap (iMagazine start) / / Note that this place is an index value. Never fill in a [I] a [start]}} private void swap (int I, int start) {int tmp = a [start]; a [start] = a [I]; a [I] = tmp;} private void print (int length) {for (int I = 0; I < length) System.out.printf +) {System.out.printf (a [I] + ");} System.out.println ();}}" what is the method of Java arrangement "is introduced here, thank you for reading.
