Translating a code from C++ to Java...?

I need some help putting this code into Java





#include %26lt;iostream%26gt;


using namespace std;





int main() {


int sales[9]= { 0 };


double gross=0, percent=0, salary=0;


int total=0;


int counter=0;


cout %26lt;%26lt; "For 5 peoples salary ranges, Enter the first gross" %26lt;%26lt; endl;


cin %26gt;%26gt; gross;


percent=gross*0.09;


salary=200+percent;


while (counter!=5) {


if (salary%26gt;=200 %26amp;%26amp; salary %26lt;= 299)


sales[0]++;


if (salary%26gt;=300 %26amp;%26amp; salary%26lt;=399)


sales[1]++;


if (salary%26gt;400 %26amp;%26amp; salary%26lt;=499)


sales[2]++;


if (salary%26gt;=500 %26amp;%26amp; salary%26lt;=599)


sales[3]++;


if (salary%26gt;=600 %26amp;%26amp; salary%26lt;=699)


sales[4]++;


if (salary%26gt;=700 %26amp;%26amp; salary%26lt;=799)


sales[5]++;


if (salary%26gt;=800 %26amp;%26amp; salary%26lt;=899)


sales[6]++;


if (salary%26gt;=900 %26amp;%26amp; salary%26lt;=999)


sales[7]++;


if (salary%26gt;=1000)


sales[8]++;


cout %26lt;%26lt; "Enter the next gross" %26lt;%26lt; endl;


cin %26gt;%26gt; gross;


counter++;


}


cout %26lt;%26lt; sales[0] %26lt;%26lt; " are in 200-299, " %26lt;%26lt; sales[1] %26lt;%26lt; " are in 300-399, " %26lt;%26lt; sales[2] %26lt;%26lt; " are in 400-499, " %26lt;%26lt; sales[3] %26lt;%26lt; " are in 500-599, " %26lt;%26lt; sales[4]

Translating a code from C++ to Java...?
Declarations of variables and main() as well as imports are also different. You can also clean up your if statements to make them more efficent (one comparison instead of two).





This is a sample class that I called stest (in stest.java) that will illustrate how to use the scanner class to read from stdin (I left out all error checking and it will allow multiple gross values to be placed on a single input line which will result in unneeded prompts, but this is just a sample). It also illustrates how you can make one test instead of two in each of your if statements.





import java.util.*;


import java.lang.*;


import java.io.*;





class stest


{


public static void main( String argv[] )


{


int sales[]; // declaration; allocation is later


String range_names[] = { "200-299", "300-399", "400-499", "500-599", "600-699", "700-799", "800-899", "900-999", "%26gt;1000" };


Scanner s; // input scanner object


int need = 5; // number of values needed


double percent = 0; // percentage commission maybe?


double salary = 0; // persons computed salary


double gross = 0; // gross sales maybe?


int idx; // index into sales





sales = new int[9]; // allocate the array (Id name this salarycount or something relative)





s = new Scanner( System.in ); // read from standard input (assume keyboard)


while( need %26gt; 0 )


{


System.out.printf( "enter gross sales for person %d: ", 6-need );


gross = s.nextInt( ); // get next int value from stdin (no error checking here)





percent = gross * 0.09; // duplication of your logic


salary = 200.0 + percent; // duplication of your logic





if( salary %26gt;= 1000 ) // working backwards needs just one


idx = 8; // comparison so more efficent


else


if( salary %26gt;= 900 )


idx = 7;


else


if( salary %26gt;= 800 )


idx = 6;


else


if( salary %26gt;= 700 )


idx = 5;


else


if( salary %26gt;= 600 )


idx = 4;


else


if( salary %26gt;= 500 )


idx = 3;


else


if( salary %26gt;= 400 )


idx = 2;


else


if( salary %26gt;= 300 )


idx = 1;


else


idx = 0;





sales[idx]++;





need--; // one less to do


}





for( idx = 0; idx %26lt; 9; idx++ )


System.out.printf( "salaries in the range of %s: %d\n", range_names[idx], sales[idx] );





}


}
