Nested For Loop in java?

Shiva Gautam August 23, 2020

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.
for(init;condition;increment)
{
    for(init;condition;increment)
     {
         System.out.print("statement");
    }
    System.out.println();
}
WAP to print the following statement?
1 2 3 4 5

A solution to This Program:
class Pattern
{
   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++;
              } 
          }
         System.out.println();   
              }       
   }
}
