Nested loops:

If a loop is combined in another loop it is said to be a nested loop. In a nested loop the inner loop gets executed completely for each iteration of the outer loop. We can have any number of levels of nested loops.

Consider the following example:

Generally to print a double dimensional array we use nested for loop.


int a[][]={ {1,2,3}, {4,5,6}, {7,8,9}};

for(int i=0;i<3;i++)



for(int j=0;j<3;j++)


System.out.print (“\t”+a[i][j]);
