nested loop in java | Pattern programs in java

In this video you will learn that what is nested loop in java. We also cover few pattern programs in this video.
When we use a loop inside another loop, then it is called as nested loop.
Generally, nested loop is used to print patterns etc.
We can use for inside for, for inside while, for inside do while. It means we can use any loop inside the other loop.
Generally we use for loop inside for loop to print patterns.

Syntax:
for(init;condition;i/d)
{ for(init;condition;i/d)
{
______;
______;
______;
}
}

1. The initialization is executed first and once only.
2. After initialization body of loop is executed.
3. After execution of body inc/dec is performed.
4. After inc/dec the condition is tested, If the condition is true then body of loop is executed, otherwise loop is terminated.
