Answer 1

importjava.util.Scanner;

class sum

{

void display();

{

Scanner sc= new Scanner( System.in);

int i, sep=0,sen=0,sop=0,son=0,n;

for ( i=1;i≤20;i++)

{

System.out.println( "Enter a number");

n=sc.nextInt();

if(n%2==0 && n<0)

{

sen=sen+n;

}

if( n%2==0 && n>0)

{

sep=sep+n;

}

if(n%2!=0 && n<0)

{

son=son+n;

}

if(n%2!=0 && n>0)

{

sop=sop+n;

}

}

System.out.println ( "Sum of negative even no.s="+sen+"\n"+"Sun of positive even no.s="+sep+"\n"+"Sum of negative odd no.s="+son+"\n"+"Sum of positive odd no.s="+sop);

}

}
