Laboratory Sheet 6 1.        Write a method to generate 1000 numbers between 1-1000. Use random number generator. Store the numbers in an array of integer. 2.        Write a method to sort numbers generated in 1. Implement selection sort . 3.        Write a method to sort numbers generated in 1. Implement bubble sort . 4.        Write a method to sort numbers generated in 1. Implement linear insertion sort . 5.        Compare the time taken to sort 1000 numbers between the three methods. 6.        Repeat 1-5, with 15000 numbers.

Method 1: x = (double)int((x+0.005)*100.0)/100.0; Method 2: x = Math.round(x*100.0) / 100.0; Method 3: DecimalFormat df2 = new DecimalFormat( "#,###,###,##0.00" ); double dd = 100.2397; double dd2dec = new Double(df2.format(dd)).doubleValue(); Method 4: f = (float) (Math.round(n*100.0f)/100.0f); Method 5: double r = 5.1234; System.out.println(r); // r is 5.1234 int decimalPlaces = 2; BigDecimal bd = new BigDecimal(r); bd = bd.setScale(decimalPlaces, BigDecimal.ROUND_HALF_UP); // setScale is immutable r = bd.doubleValue(); System.out.println(r); // r is 5.12 source:  http://salmanjamali.blogspot.my/2008/01/java-rounding-off-to-2-decimal-places.html            :http:// www.thescripts.com
