java 数组去掉重复数据和排序

package arry; public class newAaay { public static void main(String[] args) { int[] arry = {90,23,45,19,23,12,12,12}; int[] b = trim(arry);

//冒泡排序法 int temp; for (int i = 0; i < b.length; i++) { for (int j = i; j < b.length; j++) { if(b[i]<b[j]){ temp = b[j]; b[j] = b[i]; b[i] = temp; } } }

//进行排序  选择排序法 int index; int value; int temp; for (int i = 0; i < b.length; i++) { index = i; value = b[i]; for (int j = i; j < b.length; j++) { if(b[j]<value){ index = j; value = b[j]; } } temp = b[i]; b[i] = b[index]; b[index] = temp; } for (int c : b) { System.out.print(c+" "); } } //去掉重复数据 private static int[] trim(int[] arry) { int t = 0; int[] newary = new int[arry.length]; for (int i = 0; i < arry.length; i++) { boolean isTrue = true; for (int j = i+1; j < arry.length; j++) { if(arry[i] == arry[j]){ isTrue = false; break; } } if(isTrue){ newary[t] = arry[i]; t++; } } int[] newArry = new int[t]; System.arraycopy(newary,0,newArry,0,t); return newArry; } }
