How can I assign the value of an int variable to the initiialization of a “for” loop
plz insert much more example for looping, array,string,methods,inhertitance,etc in java
for (int i=10;i>=1;i–){
for (int j=1;j<=i;j++){
System.out.print(” “);
}for (int j=10;j>=i;j–){
System.out.print(“*”);
}for (int l=9;l>=i;l–){
System.out.print(“*”);
}System.out.println();
}
for (int i=8;i>=0;i–){
for (int j=9;j>=i;j–){
System.out.print(” “);
}for (int k=0;k<=i;k++){
System.out.print(“*”);
}for (int j=1;j<=i;j++){
System.out.print(“*”);
}System.out.println();
}
}
}

for(int i=0;i<=8;i++)
{
for(int j=0;j<=i;j++)
{
System.out.print(“*”);
}
System.out.println();
}
for(int i=8;i>=0;i–)
{
for(int j=0;j<=i;j++)

System.out.print(“*”);
}
System.out.println();
}
While applying a for loop i am getting the output elements one below the other . What should I do to get the out put in a single row?
