Foreword:

        Sort out some sample questions in java.

Online compilation: entry

System.out.println and System.out.print of java Personal online test code tool sharing: Entry Personal understanding: System.out.println() == The front-end console.log is the specific meaning of the print content: System is a class, and out is a static constant of the PrintStream type under the System class; . .. https://blog.csdn.net/qq_41619796/article/details/123066958

Realize the effect:

The output of the following program segment is:

public class TestArray {
	public static void main(String[] args) {
		int i,j;
		int a[] = {5,9,6,8,7};
		
		for(i=0;i<a.length-1;i++){
			int k = i;
			for(j=i;j<a.length;j++){
				if(a[j]>a[k]) k=j;
				
				int temp = a[i];
				a[i] = a[k];
				a[k] = temp;
			}
			
			for(i=0;i<a.length;i++){
				System.out.print(a[i]+" ");
				System.out.println();
			}
			
			
		}
	}
}
