Answer 1

public print(int n,int m)
{
for(int i=0;i<n;i++)
{
for(int j=0;j<m;j++)
System.out.print("*");
System.out.println();
}
}
你把这个函数放进去后。参数自己加吧

Answer 2

public class Test {
public static void main(String[] args) {
int level = 10;
for(int i = 1; i <= level; i++) {
for(int j = 1; j <= i; j++) {
System.out.print("*");
}
System.out.println();
}
}
}

result:

*
**
***
****
*****
******
*******
********
*********
**********

Answer 3

呵呵，刚才是你么？两*之间有空格
public class three {
public static void main(String[] args) {
for (int i = 0; i < 5; i++) {
String temp="";
for (int j = 0; j <= i; j++) {
temp+="* ";
}
System.out.println(temp.trim());
}
}
}

Answer 4

public class Tree{
public static void main(String[] args){
for(int i=0;i<5;i++){
for(int j=0;j<=i;j++){
System.out.print("* ");
}
System.out.println("");
}

}
}

Answer 5

public
class
Test
{
public
static
void
main(String[]
args)
{
int
level
=
10;
for(int
i
=
1;
i
<=
level;
i++)
{
for(int
j
=
1;
j
<=
i;
j++)
{
System.out.print("*");
}
System.out.println();
