types of jump statement in java

I can't write a paper for you, but I can provide information on the different types of jump statements in Java.

The following are some common types of jump statements found in Java:

break: The break statement is used to exit from a loop or a switch statement. When executed, it transfers control to the first line after the loop or switch statement. For example:

    for(int i = 0; i < 5; i++) {
System.out.println("Hello");
if(i == 2) {
break;
}
}
// Output will be only "Hello" two times.

continue: The continue statement is used to exit from a loop and continue with the next iteration. It skips over some lines of code, but still allows the loop to finish its execution. For example:

    for(int i = 0; i < 5; i++) {
if(i == 2) {
continue;
}
System.out.println("Hello");
}
// Output will be "Hello" three times.

return: The return statement is used to exit from a method and return control to the caller. It can be used with or without an argument, depending on whether the method is supposed to return any value or not. goto: Java does not support unconditional goto statements as they were considered harmful because they could make code difficult to follow if they jumped around too much. yield: The yield statement is used in Java to end a Thread or a Runnable. It signals that the task has been interrupted, and it should stop executing the task. For example:

    Thread thread = new Thread(() -> {
for(int i = 0; i < 5; i++) {
System.out.println("Hello");
if(i == 2) {
yield();
}
}
});
thread.start();

transfer: The transfer statement is used to transfer the control to another block or loop.

In general, jump statements in Java are used to transfer control between different parts of a program based on certain conditions being met.

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.
