Nested For Loop in java?
Nested For Loop means we will write more than one for loop using nested sequence.it has a collection of inner for loop and outer for loop,
The outer for loop will execute once but the inner for loop will continuously be executed.
The outer for loop will execute once but the inner for loop will continuously be executed.
for(init;condition;increment)
{
for(init;condition;increment)
{
System.out.print("statement");
}
System.out.println();
}

public static void main(String args[])
{
for(int i=1;i<=5;i++)
{
int asc=65;
for(int j=1;j<=6-i;j++)
{
if(j%2!=0)
System.out.print((char)asc+" ");
else
{
System.out.print((char)(asc+32)+" ");
asc++;
}
}
