Question

Answer 1

public static void main(String[] args)
{
int[]a=new int[5];
gen(a);

for(int i = 0; i < a.length; i++)
{
System.out.print(a[i]+"");
}

Scanners=new Scanner(System.in);

System.out.println("
enterindex of element to delete");

intind;
while(s.hasNextInt())
{
if((ind=s.nextInt())<a.length)
{
a=delete(ind,a);
}
else
{
System.out.println("indexerror");
}
}
}

/**
* fill array with random values
* @param a
*/
publicstatic void gen(int[] a)
{
for(inti=0;i<a.length;i++)
{
a[i]=(newRandom()).nextInt(100);
}
}
/**
* delete element from array with index i
* @param i
* @return
*/
publicstatic int[] delete(int i, int a[])
{
int[]arr=new int[a.length-1];
intcnt=0;

for(int j = 0; j < a.length; j++)
{
if(j!=i)
{
arr[cnt]=a[j];
cnt++;
}
}

//printsupdated array
for(int j = 0; j < arr.length; j++)
{
System.out.print(arr[j]+"");
}
System.out.println();

returnarr;
}
