  • computingMayank aka Flash October 8, 2011 at 5:18 PM

    beter and simple! [code] import java.io.*; class insertion { public static void main() throws IOException { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br= new BufferedReader(isr); System.out.println("Please Enter the number of values"); int a=Integer.parseInt(br.readLine()); int age[]=new int[a]; int minelem=0, temp; System.out.println("Enter the VALUES"); for(int x=0;x<a;x++) { age[x]=Integer.parseInt(br.readLine()); } System.out.println("The number in ascending order are: "); int min; for(int x=0;x<a-1;x++) { min=age[x]; for(int y=x+1;y<a;y++) { if(min>age[y]) { min=age[y]; minelem=y; } } System.out.println("Minimum Value: " + min); temp=age[minelem]; age[minelem] = age[x]; age[x]=temp; } for(int w=0;w<a;w++) { System.out.println(age[w]); } } } [/code]

  • This CodeAndy June 27, 2012 at 7:49 AM

    I don't know who wrote the above code, but its pretty bad. I've been programming java for only 2 years and have fixed this code up. why does insertion_srt() need a parameter for the length of the array? the method can just use array.length. I dont normally comment on things like this, but this code was soo bad i had to. please fix it up so future users are not confused by the useless complexity of the code
