- Printing numbers in the order : 1,10,2,9,3,8,4,7,5,6
public class AlternateNumbers {
public static void main(String[] args) {
// TODO Auto-generated method stub
int j=10;
for(int i=1;i<=5;i++) {
System.out.print(i+" "+j+" ");
j--;
}
}
}
2.Using array Printing numbers in the order : 1,10,2,9,3,8,4,7,5,6
public class Alternatenumberpattern {
public static void main(String[] args) {
// TODO Auto-generated method stub
int[] a= {1,2,3,4,5,6,7,8,9,10};
int n=a.length;
int m=n-1;//last index
for(int i=0;i<n/2;i++) {
System.out.print(a[i]+" "+a[m-i]+" ");
}
}
}
3.Using array Printing numbers in the order : 1 -1 1 -1 1 -1 1 -1
public class Patternalternative0and1 {
public static void main(String[] args) {
int[] a= {1,1,1,1,-1,-1,-1,-1};
int n=a.length;
int m=n-1;//last index
for(int i=0;i<n/2;i++) {
System.out.print(a[i]+" "+a[m-i]+" ");
}
}
}
Same way we can do for this array: int[] a= {1,1,1,1,0,0,0,0};
