Write a complete java program that printout the following pattern using nested loops:
1
2 1
3 2 1
4 3 2 1
5 4 3 2 1
6 5 4 3 2 1
I have this:
public class trying {
/** Main method */
public static void main(String[] args) {
//count down from 5
for (int i = 7 ; i >= 1; i–) {
System.out.println();
//count down from 6
for (int j = 7- i; j >= 1; j–) {
System.out.printf(“%4d”, j);
}
}
}}
but it prints this:
1
2 1
3 2 1
4 3 2 1
5 4 3 2 1
6 5 4 3 2 1

public class pattern {
public static void main(String args[]){
int n=6,j,k,i;
//outer loop to print six lines
for(i=1;i<=n;i++){
// this loop to print spaces
for(j=(n-i);j>=1;j–)
System.out.print(” “);
//this loop to print numbers
for(j=i;j>=1;j–)
System.out.print(j+” “);
System.out.println();
}
}
}
