In Java, you can nest any type of loop within another loop. The types of loops in Java are for, while, and do-while. Here’s a brief explanation of each type of nested loop
Nested For Loops
A nested for loop is a loop inside another for loop. The inner loop executes its iterations for each iteration of the outer loop.
Nested For Loops
for(int i = 0; i < 5; i++) { // Outer for loop
for(int j = 0; j < 5; j++) { // Inner for loop
System.out.print("* ");
}
System.out.println();
}
Nested While Loops
A nested while loop is a while loop inside another while loop. The inner loop executes its iterations for each iteration of the outer loop.
Nested While Loops
int i = 0;
while(i < 5) { // Outer while loop
int j = 0;
while(j < 5) { // Inner while loop
System.out.print("* ");
j++;
}
System.out.println();
i++;
}
Nested Do-While Loops
A nested do-while loop is a do-while loop inside another do-while loop. The inner loop executes its iterations for each iteration of the outer loop.
Nested Do-While Loops
int i = 0;
do { // Outer do-while loop
int j = 0;
do { // Inner do-while loop
System.out.print("* ");
j++;
} while(j < 5);
System.out.println();
i++;
} while(i < 5);
Mixed Nested Loops
You can also mix different types of loops. For example, you can have a for loop inside a while loop, or a do-while loop inside a for loop, and so on.
Lets see the mixed nested loops in next one.
Remember, when using nested loops, each type of loop can be controlled with its own unique condition, providing flexibility in how your Java program executes loops.
