name two jump statements in java

I'm happy to help!

In Java, there are several types of control flow statements that allow developers to control the execution of their code. Two fundamental jump statements in Java are break and continue.

1. Break Statement

The break statement is used to exit a loop or a switch block prematurely. When a break statement is encountered, the loop or switch block will terminate immediately, skipping any remaining iterations or cases.

For example:

for (int i = 0; i < 10; i++) {
if (i == 5) {
break; // Exit the loop when i reaches 5
}
System.out.println(i);
}

In this example, the break statement will exit the loop when i equals 5. The remaining iterations of the loop will be skipped.

2. Continue Statement

The continue statement is used to skip the current iteration of a loop and move on to the next one. When a continue statement is encountered, the execution of the code within the current iteration will terminate, and control will pass to the next iteration.

For example:

for (int i = 0; i < 10; i++) {
if (i == 5) {
continue; // Skip this iteration when i equals 5
}
System.out.println(i);
}

In this example, when i equals 5, the continue statement will skip the current iteration and move on to the next one. The code within the loop will not execute for i = 5, but it will still print the values of i from 6 to 9.

When to Use Each

In general, you would use a break statement when you want to exit a loop or switch block entirely, whereas a continue statement is used to skip an iteration and move on to the next one. Here are some rules of thumb:

Use break when: You need to exit a loop or switch block prematurely. You have a conditional statement that will always be true after a certain point, making it unnecessary to continue iterating. Use continue when: You want to skip an iteration and move on to the next one based on a condition. You need to re-evaluate the loop condition or switch case.

By using these jump statements effectively, you can write more efficient and readable code in Java!

jump statements in java with example

I'll respond in English this time!

In Java, jump statements are used to transfer control to a different part of the program. There are four types of jump statements:

break: Used to exit a loop or switch statement.

Example:

for (int i = 0; i < 5; i++) {
if (i == 3) {
break;
}
System.out.println(i);
}

Output: 0, 1, 2

In this example, the loop will exit when i reaches 3.

continue: Used to skip the rest of the current iteration and move on to the next one.

Example:

for (int i = 0; i < 5; i++) {
if (i == 2) {
continue;
}
System.out.println(i);
}

Output: 0, 1

In this example, the loop will skip the iteration when i is 2 and move on to the next one.

return: Used to exit a method or constructor and return control to the calling method or program.

Example:

public int add(int a, int b) {
if (a < 0 || b < 0) {
return -1; // Return an error code
}
return a + b;
}

In this example, the return statement will exit the method and return -1 to indicate an error.

goto: Used to transfer control directly to a labeled statement in the same method or constructor.

Example:

public void process() {
label1:
for (int i = 0; i < 5; i++) {
System.out.println(i);
if (i == 3) {
goto label2;
}
}
label2:
System.out.println("End of loop");
}

In this example, the goto statement will transfer control directly to the labeled statement (label2) when i reaches 3.

Note that goto is generally considered bad practice and should be avoided in favor of other control flow statements.
