Nested Loops in Java | Syntax, Flowchart & Prime Number Program
Nested Loops in Java explained in the simplest way! In this video, you’ll learn nested for loops in Java, their syntax, flowchart, and a step-by-step prime number program—perfect for ICSE Class 9 & 10 students and Java beginners.
If you’ve ever wondered what are nested loops in Java and why they are needed, this lesson will clear all your doubts with logic, diagrams, and clean coding examples.
In this Java tutorial, we begin with the basics of nested loops and explain the need of nested loops in Java using beginner-friendly examples. You’ll understand how a loop inside a loop works and where nested for loops are used in real ICSE exam programs. Special attention is given to iteration in Java, control statements, and logic building, which are crucial for board exams and competitive thinking.
Next, we break down the syntax of nested for loop in Java and explain it line-by-line, followed by a nested for loop flowchart as per the ICSE Computer Applications syllabus. Flowcharts and algorithms are frequently asked in exams, so this section is especially useful for Java board exam preparation.
Finally, we solve a prime numbers program using nested loops in Java. You’ll learn the prime number logic in Java, perform a dry run of nested loops, and then write the complete Java program to print prime numbers in a given range. This makes the video ideal for Java nested loops for beginners, Class 9 Java, and Class 10 Java students looking for exam-oriented clarity.
