Try this one
试试这个
public static void main(String[] args)
{
int x=11;
int y=x/2; // spaces
int z=1; // *`s
for(int i=0;i<5;i++)
{
for(int j=0;j<y;j++)
{
System.out.print(" ");
}
for(int k=0;k<z;k++)
{
System.out.print("*");
}
y=y-1;
z=z+2;
System.out.println();
}
}

You can try in this way.
你可以试试这个方法。
for(int a=5;a>0;a--){
int b=0;
for(b=0;b<a;b++){
System.out.print(" ");
}
for (int j=b;j<5;j++){
System.out.print(" $ ");
}
System.out.println("");
}
Out put
输出
$

n=s.nextInt();
temp = n;
for ( row = 1 ; row <= n ; row++ )
{
for ( c = 1 ; c < temp ; c++ )
System.out.print(" ");
temp--;
for ( c = 1 ; c <= 2*row - 1 ; c++ )
System.out.print("*");
System.out.println("");

A better pyramid can be printed this way:
一个更好的金字塔可以这样打印：
The Pattern is
$
$$$
$$$$$
$$$$$$$
$$$$$$$$$
$$$$$$$$$$$
public static void main(String agrs[]) {
System.out.println("The Pattern is");
int size = 11; //use only odd numbers here
for (int i = 1; i <= size; i=i+2) {
int spaceCount = (size - i)/2;
for(int j = 0; j< size; j++) {
if(j < spaceCount || j >= (size - spaceCount)) {
System.out.print(" ");
} else {
System.out.print("$");
}
}
System.out.println();
}
}

for (int k = 1; k <= size; k++) {
for (int i = (size+2); i > k; i--) {
System.out.print(" ");
}
for (int j = 1; j <= k; j++) {
